To provide a method for producing a porous calcium phosphate body having open micropores. A porous calcium phosphate body having open and uniform micropores can be produced by the method for producing the porous calcium phosphate body, in which calcium phosphate is subjected to electrospinning.


An inner surface-modified tube includes fine particles that are buried in an inner surface of a tube with part of surfaces of the fine particles exposed, wherein the fine particles are unevenly distributed such that more fine particles are distributed in a region from a center of the tube to the inner surface of the tube than in a region from the center of the tube to an outer surface of the tube based on a thickness direction of the tube, an arithmetic average roughness Ra of the inner surface of the tube is 1 nm or more and 100 m or less, a particle diameter of each fine particle is 10 nm or more and 100 m or less, and an inner diameter of the tube is 0.01 mm or more and 100 mm or less.


Silver particles are prepared by aggregating silver ions in accordance with a method including steps of (a), in preparing a mixed solution by adding a thiol compound to a solution containing silver ions, adjusting an amount of the thiol compound added to the solution and (b) adding a reducing agent to the mixed solution. This allows a particle size and antibacterial activity of the silver particles to be easily adjusted.
