Power transmission unit and power transmission coil

A power transmission unit comprising:

• a power transmission coil that transmits electric power in a non-contact manner;
• a communication part that is formed in an annular shape about an axis, arranged to surround the power transmission coil, and transmits and receives a signal;
• and
• a shielding member that is formed in an annular shape about the axis, arranged between the power transmission coil and the communication part in an intersecting direction intersecting with the axis, and shields magnetic force generated by the power transmission coil, wherein
• the shielding member is overlapped with the power transmission coil and both sides thereof in an axial direction along the axis direction are opened and co-planar with at least parts of the power transmission coil and the communication part when viewed from the intersecting direction.
