A non-contact power supply control system includes: an electric transmission pad connected to a power source unit; a control unit controlling current supply to the electric transmission pad; a living body detecting means detecting a living body present around the electric transmission pad; a power receiving pad magnetically coupled to the electric transmission pad to excite power, when current is supplied from the power source unit to the electric transmission pad; and a power storage unit storing power excited by the power receiving pad. The living body detecting means are arranged on the road surface side, and the control unit, when determining that no living body is present around the electric transmission pad on the basis of a result from the living body detecting means, controls the power supply unit to supply power to the power storage unit.
