PURPOSE: To obtain a non-contact connector which is small in leakage flux and coil area, easily designed, and capable of doing with a coil of one kind by a method wherein the non-contact connector is equipped with a core which is held by a board forming a ring-shaped magnetic circuit together with a counter connector to serve as a magnetic path.

CONSTITUTION: A recessed part 12 open on a connecting section 15 side is provided to a connector 10, a core 1 is housed in the recessed part 12 and fixed, and a board 11 provided with circular coil patterns 13a and 13b of different types formed surrounding through-holes 14a and 14b is made to overlap the connector 10. The same as above, a recessed part 22 open on a connecting section 25 side is provided to a connector 20, a core 1 is housed in the recessed part 22 and fixed, and a board 21 provided with circular coil patterns 23a and 23b of different types formed surrounding through-holes 24a and 24b is made to overlap the connector 20. The connection sections 15 and 25 are made to overlap each other, whereby the cores 1 and 1 form a ring-shaped magnetic path joining the end faces of their opposed first and second legs, 2a and 2b, together.
