NON-CONTACT TYPE ELECTRIC POWER TRANSMISSION COIL MODULE AND BATTERY PACK EQUIPPED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a non-contact type electric power transmission coil module capable of reducing amount of leakage flux between both coil modules in which coils are oppositely arranged in a state of facing each other.

SOLUTION: A secondary side coil module 35 comprises: a first coil 41 planarly winding a conductive wire; and a magnetic sheet 40 on which the first coil 41 is disposed. The magnetic sheet 40 has: an inner projection part 43 projected from a plane part 42 at an air-core part 45 of the first coil 41; and an outside projection part 44 projected from the plane part 42 in the outside of the first coil 41.
