a coil for power transmission;
a power transmission circuit which supplies power to the coil;
at least one shielding member which shields an electromagnetic field of the coil; and
a hole provided to the shielding member, wherein
an equivalent circle diameter of the hole is equal to or less than 1.5 times of an interval between the coil and the shielding member to which the hole is provided, and
the equivalent circle diameter of the hole is equal to or greater than 0.4 times of the interval between the coil and the shielding member to which the hole is provided.
