VEHICLE NON-CONTACT POWER FEEDING SYSTEM

A contactless electricity supply system for a vehicle includes a power transmitter coil unit (12) provided on a ground-side and a lifting device for lifting up the power transmitter coil unit (12) from the ground. The power transmitter coil unit (12) supplies electricity to a power receiving coil unit (22) by magnetic coupling therewith. The power transmitter coil unit (12) includes a case (123) that houses a power transmitter coil (120). A bulge (123a) is formed on an upper face of the case (123) around a winding center axis (O) of the power transmitter coil (120) wounded in a planar manner in a plan view.
