A contactless electric power transmission system includes an electric power reception device, a control device, a first temperature sensor, and a second temperature sensor. The electric power reception device includes a housing, a secondary side coil, a core member, and a substrate on which an element is mounted. The first temperature sensor detects a temperature of external air in contact with a surface of the housing. The second temperature sensor detects a temperature of the substrate. The control device estimates at least a temperature of the secondary side coil based on a thermal model of a coil unit and a detection value of the temperature output from each temperature sensor and controls electric power received from an electric power transmission device in response to the temperature of the secondary side coil.
