A wireless power supply coil unit for transmitting or receiving power wirelessly includes a coil having a hollow portion and a coil axis in a vertical direction, a first magnetic body having an opening at a position corresponding to the hollow portion of the coil, a second magnetic body having a plate-like shape and arranged in the hollow portion of the coil on one side of the first magnetic body, and an insulating plate interposed between the first magnetic body and the second magnetic body. The coil unit has high surface stiffness of the magnetic bodies and prevents or reduces dielectric breakdown between contact surfaces of the magnetic bodies.
