Abstract
A charging circuit includes a first energy harvesting element that performs energy harvesting and supplies a current to a power storage element, a second energy harvesting element that performs energy harvesting, the second energy harvesting element is made in materials same as the first energy harvesting element, and a first switch that is disposed in a current path between the first energy harvesting element and the power storage element and that is put into an off-state, in a case where a first output voltage of the second energy harvesting element is smaller than a first value, thereby cutting off the current path.
