A method for controlling a power transmitting device includes (1) causing a power transmitting coil to output power before a power receiving coil and the power transmitting coil are electromagnetically coupled with each other and a mobile object including the power receiving coil overlaps the power transmitting coil in order for the power receiving coil and the power transmitting coil to be electromagnetically coupled with each other, (2) causing a thermal sensor to measure a surface temperature of the metal foreign object, and (3) causing, if the measured surface temperature of the metal foreign object is equal to or higher than a threshold, the power transmitting coil to reduce the power to be output or stop outputting the power.
