[Problem] To provide a magnetostrictive member that has high parallel magnetostriction and little variation in parallel magnetostriction from member to member and that, when incorporated into a magnetostrictive vibration power generation device, produces high device output and suppresses variation in optimum magnetic field strength as device characteristics. [Solution] A magnetostrictive member according to the present invention is formed from a plurality of identical crystals. The magnetostrictive member is a plate-shaped body that comprises crystals of a magnetostrictive iron alloy and has a long direction and a short direction. At least one of a front surface and a back surface of the plate-shaped body has a plurality of grooves that extend in the long direction. The ratio (standard deviation/average) between the standard deviation of the optimum magnetic field strengths found for a plurality of the magnetostrictive members by electromechanical equivalent circuit analysis and the average of the optimum magnetic field strengths is no more than 0.2.

The present invention provides a method and apparatus for forming a zinc oxide thin film with high transparency and high conductivity on a surface of a flexible substrate such as plastic without the indispensable requirement of doping impurities. In the method of forming a zinc oxide thin film by reacting oxygen radicals and zinc atoms on a surface of a substrate placed in a film-forming chamber evacuated to a vacuum, the density of crystal defects that are defects of the atomic arrangement of the zinc oxide thin film is controlled by the temperature of the substrate, and the zinc oxide thin film is thereby formed. It is suitable to form the film while maintaining the temperature of the substrate at 400° C. or less to intentionally disturb the regularity of the atomic arrangement of the zinc oxide thin film.
