Abstract

A wireless power feeding device includes first to Nth (N is an integer of 2 or more) switching elements connected in parallel to each other between a power line, which is connected to one end of a power transmission coil, and a ground line, each of the first to Nth switching elements supplying a current to the drive line in accordance with an oscillation signal; a first resistor connected in series with the first switching element between the power line and the ground line; and a current measurement circuit for generating a first measured current signal representing the amount of the drive current on the basis of the potential of one end of the first resistor.
