  • a method for electrically energizing an energization-operated toy element and an energizing operation toy which are characterized in that an electric double layer capacitor 31 is employed as energization means for electrically energizing a toy element which is operated upon application of low voltage, the capacitor is charged upon reception of a current from a DC power source, and the charged electric power is used to electrically energize a toy load as a discharge current to operate the toy element.
  • an energization heat generation color changing toy which comprises: an energization heat generation color changing element provided with a resistant heating member for generating heat upon application of DC voltage and a thermal color changing layer disposed in contact with or close to said heating member, energization means 3 consisting of the electric double layer capacitor for supplying a discharge current to the resistant heating member to generate heat; and a power source for charging said capacitor by supplying DC voltage from 0.5 V to 9.0 V to the capacitor.
  • a method for electrically energizing an energization-operated toy element which is characterized in that the electric double layer capacitor is interposed in the route to the power source as the energization means for electrically energizing the toy load which is operated upon application of low voltage and said electric double layer capacitor is charged upon reception of a DC current from the power source to send a discharge current to energize and operate the toy load.
