PROBLEM TO BE SOLVED: To provide a power generator used for various kinds of electronic apparatuses in which the number of components can be reduced and which has a magnetic circuit configuration part of configuration capable of reduction in size in accordance with the side in the slide direction. ! SOLUTION: In a power generator, the upper member 60 and the lower member 70 in a Z-shape when viewed from the upper surface are firmly fixed onto a permanent magnet 50 whose upper surface is an N-pole and lower surface is an S-pole, a magnetic circuit configuration part is provided, composed of a magnetic member with a coil formed by winding a coil 100 around wall parts 81 of a coil holding member 80 in which the central straight line portions are arranged, and external members 111, 112 which are arranged in outward positions of protrusions 62, 72 and 73, 63 protruding to left and right of the magnetic member with the coil, respectively, and synchronized with each other to be slidably moved, and power generatio |
