PROBLEM TO BE SOLVED: To provide a cordless power source apparatus which can be placed on a countertop without installing any plug outlet on walls, etc. for being used as a power source, can be removed when not in use to avoid being a hindrance, and by which the countertop can be widely used by being flattened. SOLUTION: The cordless power source device 1 is made by placing a primary coil unit 2 which is at least equipped with a primary electromagnetic induction coil 5 on a power transmission side and an inverter circuit 10 that energizes and excites the primary coil 5, and a coaster-type adaptor 3 which is at least equipped with a secondary coil 17 on a power receiving side and a plug outlet section 18, facing each other across a countertop 32 of a kitchen unit etc. The coaster-type adaptor 3 is then placed at a specified position on the countertop 32 when it is to be used as a power source and can be removed from the countertop when not in use.
