PROBLEM TO BE SOLVED: To provide a power generation device which uses a piezoelectric element, is used for gas cooking stove and an electronic lighter and improves efficiency by using output of the piezoelectric element by which a gas is combusted by incurring an ignition spark.SOLUTION: A storage battery, a first switch for turning on and turning off the storage battery and a power generation device connected with the first switch are included. The power generation device includes: a second switch SW2 which is instantaneously turned on under control of a microcomputer connected with a transformer providing a voltage desired by an electret; the electret connected with the second switch; and a power generation part in which a coil is wound around an iron core bonded to the piezoelectric element coupled with the electret and which extracts output to the outside. |
