A copper alloy wiring film of a flat panel display of the present invention and a sputtering target for forming the same have a composition including Mg: 0.1 to 5 atom %; either one or both of Mn and Al: 0.1 to 11 atom % in total; and Cu and inevitable impurities as the balance, and if necessary, may be further including P: 0.001 to 0.1 atom %.

Provided are a metal nitride material for a thermistor, which has a high reliability and high heat resistance and can be directly deposited on a film or the like without firing, a method for producing the same, and a film type thermistor sensor. The metal nitride material for a thermistor consists of a metal nitride represented by the general formula: (M

A plurality of cutting edges that are arranged on an outer circumference of a shaft-shaped broach body are provided with a spline teeth group, which contains a plurality of spline teeth 8 that groove a prepared hole of a work material, and a round teeth group, which is disposed in a different position from the spline teeth group along an axis direction and contains a plurality of round teeth that machine an inner circumference of the prepared hole. At least one gullet is formed to extend along the outer circumference of the broach body in a circumferential direction around the axis between the round teeth that are adjacent to one another in the axis direction in the round teeth group. The gullet extends toward the axis direction, gradually twisting toward the circumferential direction. The spline teeth group and the round teeth group are formed integrally on the outer circumference of the broach body.
