  "textContent": "A wireless power reception device detects a power receiving coil position relative to a power transmitting coil while curbing an increase in power loss. The wireless power reception device includes: a power receiving coil magnetically coupled to the power transmitting coil; a first rectification and smoothing circuit rectifying an AC voltage supplied from the power receiving coil and outputs the rectified AC voltage to a load; first and second capacitors respectively connected to first and second transmission lines; a first resistor having one terminal connected to the first capacitor and the other terminal is supplied with a predetermined reference potential; a second resistor having one terminal connected to the second capacitor and the other terminal is supplied with the reference potential; and a position detecting circuit detecting the power receiving coil position relative to the power transmitting coil on the basis of first and second junction point potentials.",
