WIRELESS POWER RECEPTION DEVICE

A magnetic coupling coefficient between a power reception coil and a communication antenna is 0.3 or less. A power management circuit suppresses electromagnetic interference between the power reception coil and the communication antenna in a predetermined time period by causing a rectification stopping circuit to operate to keep the rectification stopping circuit in an operation state in the predetermined time period with a received power voltage exceeding a first threshold value and by changing a resonant frequency of a power reception resonant circuit to a frequency different from a frequency being used in a wireless communication circuit to keep the resonant frequency in a changed state.
