PROBLEM TO BE SOLVED: To provide a power reception device in which a magnetic core of a power reception inductor can be detachably provided, and a connection connector of a detachable part has a simple configuration.SOLUTION: A power reception device according to the present embodiment comprises: a power reception inductor for wirelessly receiving power by mutual inductance from a power transmission device; a capacitor part connected to the power reception inductor; a rectifier for converting alternating-current power received via the capacitor part into direct-current power; a communication part for performing communication with the power transmission device on a power transmission state or a power reception state; a sensor part for performing at least one of detection of reception power, detection of an alien substance, and detection of temperature; and a control part for controlling the reception power on the basis of reception information of the communication part or a detection result of the sensor part. The power reception inductor includes a magnetic core, a coil winding part, and a conductive plate. The magnetic core is provided in the detachable part provided in a housing of the power reception device so as to be detached therefrom, and the sensor part is provided outside the detachable part.SELECTED DRAWING: Figure 1
