SHIELD MEMBER AND POWER TRANSMISSION UNIT

A shield member and a power transmission unit each include a shielding wall formed annularly about an axis so as to surround a power transmission coil at a position extending along an intersecting direction. The shielding wall shields a magnetic force generated by the power transmission coil. The shielding wall is formed such that a distance between wall faces facing each other in the intersecting direction is wider at a longer distance from a first side toward a second side in an axial direction.
