To provide a self-generating article capable of certainly lighting a light-emitting diode by using vibrations of external energy, pressure, wave power, wind power, magnetic force and the like, transmitting them as extension/retraction force, suction force, repulsion, and vibration and the like, and continuing and amplifying them.

A power-generating magnet, a cushion, and a suction magnet are inserted in a pipe. Both ends of the pipe are covered by upper and lower covers, and a coil is attached to the outside of the pipe. A control box and a light-emitting diode are attached to a wire extracted from the coil, and inserted in a case, thereby configuring a power-generating magnet assembly. A saddle and the like are attached to the case. If the saddle is attached to clothes of a person or a necklace of a pet, by vibrations of the person or the ped, the power-generating magnet in the pipe reciprocates the upper and lower ends of the coil to generate electricity. The electricity is made to flow through a bridge diode existing in the control body to rectify, and the current always in the same direction is made to flow through the light-emitting diode 11 at a terminal to light up.
