To provide a power generator capable of generating power by easily controlling temeperature, and excellent in safety; and an in-vehicle energy regeneration device equipped with the power generator.
A power generator 1 includes: a first magnetic material 2 which is fixedly arranged: a second magnetic material 3 which is arranged oppositely to the first magnetic material 2 so as to repulse or attract the first magnetic material 2, and capable of approaching and separating from the first magnetic material 2; a storing cylinder 4 for storing the first magnetic material 2 and the second magnetic material 3; a heating device 5 for raising/lowering a temperature of the first magnetic material 2 and/or the second magnetic material 3; a holding device 6 for holding the second magnetic material 3 in a state approaching and/or separating from the first magnetic material 2; and a power take-out device 7 having a coil 8 wound around an outer peripheral surface of the storing cylinder 4, and taking out induced electromotive force generated by vibrations of the second magnetic material 3 when the temperature of the first magnetic material 2 and/or the second magnetic material 3 is raised/lowered by the heating device 5.
