POWER TRANSMISSION UNIT AND POWER TRANSMISSION COIL

A power transmission unit includes: a power transmission coil; a communication coupler that is formed in an annular shape about an axis X and arranged to surround the power transmission coil; and a shielding member that is formed in an annular shape about the axis X, and arranged between the power transmission coil and the communication coupler in an intersecting direction. The shielding member is arranged at a position along the intersecting direction to surround the power transmission coil, and shields magnetic force generated by the power transmission coil.
