A power receiver includes an outer case shaped to house a secondary battery, a power reception coil member disposed in the outer case, and a circuit board disposed in the outer case. On the circuit board, a power reception circuit electrically connected to a coil conductor of the power reception coil member and a charging circuit configured to charge and discharge the secondary battery are provided. The outer case includes a first outer case member near the power reception coil member and a second outer case member forming the outer case in combination with the first outer case member. The first outer case member has, for example, a flat surface, is disposed nearer to an external power transmission coil than the second outer case member, and has a structure with which the coil conductor of the power reception coil member and the power transmission coil can face each other.
