A power reception apparatus includes a power reception coil, a relative distance detection section, a power transmission efficiency detection section, a database, a power transmission frequency setting section, and a power transmission request section. The power transmission frequency setting section is configured to read from the database a resonance frequency corresponding to a combination of a relative distance and an initial transmission efficiency and to set the read resonance frequency as a power transmitting frequency. The power transmission request section is configured to notify the power transmission apparatus of the power transmission frequency set by the power transmission frequency setting section to request wireless power transmission with the power transmission frequency.
