Abstract
A luminous toy capable of emitting light at any time anywhere without having to worry about a power shortage and failing to turn off a switch and capable of preventing environmental pollution. The luminous toy includes a toy body provided with a piezoelectric element which induces a voltage when it is strained, a rectifying circuit for rectifying the voltage generated from the piezoelectric element, a capacitor for smoothing the voltage rectified by the rectifying circuit and a luminous element connected in parallel to the capacitor. The luminous toy also includes a strain generating mechanism for generating strain for straining the piezoelectric element.
