PROBLEM TO BE SOLVED: To provide a vibration power generator which continuously and smoothly moves a permanent magnet in a bobbin thereby inhibiting deterioration of the generation efficiency and the reliability, and to provide a manufacturing method of the vibration power generator.SOLUTION: A vibration power generator 1 includes units 10, 20. The units 10, 20 are housed in a housing 2 being arranged in an axial direction. The units 10, 20 respectively include bobbins 11, 21. Coils 14, 24 are respectively wound around the bobbins 11, 21. A permanent magnet 31 is provided in the bobbins 11, 21 so as to reciprocate. Inclination parts 15B, 25B are respectively provided at end terminal parts 13, 23 provided at contact portions of the bobbins 11, 21. The inclination part 15B, 25B form a groove 42 with the end terminal parts 13, 23 contacting with each other. A lubricant 51 applied to an inner wall of a hallow part 41 is accumulated in the groove 42. |
