A power reception coil device is a power reception coil device attached to a movable body, for wirelessly receiving power from a power transmission coil device, and includes a power reception coil portion including a conductive wire, and a nonmagnetic body disposed between the movable body and the power reception coil portion. The nonmagnetic body includes a first overhang protruding in a first direction outwardly from one end portion of a region onto which the power reception coil portion is projected in a second direction. The first direction is orthogonal to the second direction in which the power reception coil device opposes the power transmission coil device. The first overhang is longer than or equal to a maximum permissible misalignment permissible between the power reception coil portion and a power transmission coil portion of the power transmission coil device.
