A control IC for first and second transmission drivers that drive a primary coil includes an output terminal connected to the first transmission driver on a first side, an output terminal connected to the second transmission driver on a second side, and an input terminal to which a waveform of a coil connection terminal is input through a waveform detection wiring pattern on a third side. The control IC is disposed in a center area of a board at a position shifted in a first direction with respect to a centerline. The coil connection terminal and a resonant capacitor are disposed in first and second row positions on the end of the board. The first transmission driver is disposed at a position shifted in the first direction with respect to the first side of the control IC. The second transmission driver is disposed at a position opposite to the second side of the control IC. The waveform detection wiring pattern extends from the third side of the control IC to the coil connection terminal through an area shifted in a second direction with respect to the centerline.
