A power transmitting device includes a power transmitting coil for providing output power to a power receiving coil, a thermal sensor that detects a temperature around the power transmitting coil, and a power transmission control circuit that controls the power transmitting device. The power transmission control circuit causes the power transmitting coil to provide first output power, the power transmitting coil to provide second output power to the power receiving coil for charging a battery connected to the power receiving coil, the thermal sensor to detect the temperature around the power transmitting coil, and, if the detected temperature is equal to or higher than a threshold because of existing a metal foreign object, the power transmitting coil to reduce a level of the output power or stop the output power. The level of the first output power is lower than the level of the second output power
