Abstract
A power supply device () is provided with a push-type power generator (). When a push-button () on the push-type power generator () is pushed, a variable voltage is generated by a piezoelectric element () that excites a primary coil (L). A high-frequency inverter () is activated by the variable voltage, exciting the primary coil (L), and an alternating field is generated from the primary coil (L). Secondary power can be supplied by means of the alternating field even if a secondary coil (L) of an electrical device (), disposed on a surface of a wall () opposite the surface on which the charging device () is disposed, is not in contact with the power supply device (). The secondary coil (L) of the electrical device () causes a light-emitting diode (LED) to illuminate using secondary power obtained by non-contact power supply.
