Abstract: A power generator including a piezoelectric element that includes a piezoelectric film, and a first electrode and a second electrode sandwiching the piezoelectric film therebetween; a deformable body that has Young's modulus larger than synthetic Young's modulus of the piezoelectric element; a first fixing member that directly fixes the piezoelectric element and the deformable body; and a second fixing member that is disposed apart from the first fixing member and fixes the piezoelectric element. The deformable body is deformed with respect to stress from outside in a direction in which a distance between the first fixing member and the second fixing member is lengthened.

Abstract: A resin composition, wherein a resin component in the resin composition has a group represented by the following General Formula (11), (21) or (31) and a urethane bond: (in the formulae, Z1 is an alkyl group, and one or more hydrogen atoms in the alkyl group may be substituted with a cyano group, a carboxy group or a methoxycarbonyl group, and two or more of the substituents may be the same as or different from each other; Z2 is an alkyl group; Z3 is an aryl group; R4 is a hydrogen atom or a halogen atom; and the bond with the symbol * is formed with the bonding destination of the group represented by General Formula (11), (21) or (31)).
