[Problem] To provide: a bactericidal agent composition which can exhibit an excellent bactericidal effect in the presence of an organic substance and against biofilms; a method for producing the bactericidal agent composition; and a sterilization method using the bactericidal agent composition. [Solution] A bactericidal agent composition which comprises water containing ultrafine bubbles having a most frequent particle diameter of 500 nm or less and a bactericidal component. Preferably, the density of most frequent particles of the ultrafine bubbles are 10,000 particles or more and the density of ultrafine bubbles each having a particle diameter of 1000 nm or less is 1,000,000 particles or more.

A paste-like thermally foaming filler contains 2 to 20 parts by weight of an uncrosslinked synthetic rubber. 5 to 30 parts by weight of a partially crosslinked rubber, 0.1 to 5 parts by weight of a quinone-based vulcanizing agent, 0.2 to 1 parts by weight of thermally expandable balloons, 1 to 10 parts by weight of a thermoplastic resin, 20 to 50 parts by weight of a plasticizer, 15 to 50 parts by weight of an inorganic filler, and 2 to 15 parts by weight of a chemical foaming agent. The paste-like thermally foaming filler exhibits high foaming capability even at low temperatures.


It is an object of this invention to provide an environmental biological allergen measurement method capable of simple and low-cost measurement of the amount of an environmental biological allergen without using anti-allergen antibodies or a special substrate, and to provide a simple biological allergen quantification kit for carrying out the method. The object can be achieved by a biological allergen measurement method characterized in that the amount of an environmental biological allergen is measured by bringing a test substance into contact with a water-soluble gel or aqueous solution containing a substrate of the protease of the environmental biological allergen, and by quantifying the physical change of the water-soluble gel or the aqueous solution caused by the effect of the protease contained in the test substance on the substrate.

A brake disc is provided capable of effectively reducing the generation of noise such as brake noise by making specifications relating to lightening holes different from each other between two brake disc plates. In the brake disc, two brake disc plates are laminated so as to slide on each other by vibration during braking, and specifications relating to one or more selected from lightening holes, plate thickness, diameter, and warpage are made different from each other between the brake disc plates. In addition, lightening holes are formed on at least one of the brake disc plates, and one or more specifications selected from the number of lightening holes, the shapes of the lightening holes, the sizes of the lightening holes, and the arrangement positions of the lightening holes are made different from each other between the brake disc plates.
