PROBLEM TO BE SOLVED: To provide a generator for a portable electronic apparatus which is simple of constitution and is excellent in power generation efficiency, being capable of automatically securing the power at necessity merely by adding vibration to the portable electronic apparatus. SOLUTION: On the technical premise of a generator for a portable electronic apparatus which is installed in a portable electronic apparatus having a battery charger and a piezoelectric generator connected to that battery charger, the above piezoelectric generator is made of a stratified piezoelectric ceramic board where plate-shaped two sheets of piezoelectric ceramic elements are joined with each other with polarization reversed, and it generates power by hitting one side or both sides of this piezoelectric ceramic board. |
