A vehicular power transmission device includes a power transmission unit which transmits electromagnetic waves to a mobile device to transmit power to a power reception unit of the mobile device, and a frequency changing unit which, when it is determined based on the transmission frequency of the electromagnetic waves to be transmitted from the power transmission unit to the mobile device and a reception frequency of a radio receiver that radio noise is generated by the power transmission unit, charges the transmission frequency of the electromagnetic waves of the power transmission unit, wherein the power transmission unit changes a transmission power of the electromagnetic waves based on an amount of change in the transmission frequency of the electromagnetic waves charged by the frequency changing unit.
