A power receiving device and power feeding device improve convenience of the user by increasing the freedom of configuring the power receiving device with respect to the power feeding device and freedom of configuring the power feeding device with respect to the power receiving device, and inhibit large size of machines. The power receiving device includes: plurality of surfaces; and inside a power receiving coil, and the power receiving coil includes: a winding portion with wires wound; and an opening portion surrounded by the winding portion and having two opposite opening ends. By disposing the power receiving coil so an end face of at least one of the two opening ends is nonparallel (excluding perpendicular) to two or more surfaces of the power receiving device, a power receiving area capable of receiving power from the power feeding device formed on the two or more surfaces of the power receiving device.

Power receiving device and power feeding device

A power receiving device, a power feeding device, and a wireless power transmission device are provided. The power receiving device receives power wirelessly transmitted from the power feeding device and includes one or more power receiving units. At least one of the power receiving units in the power receiving device is disposed along two or more surfaces which form the outer shape of the power receiving device and are not parallel to each other.
