A power transmission coil unit 1 includes a power transmission coil 2 and a power supply member 3 electrically connected to a power source and power transmission coil 2. The power supply member 3 is provided with a first metal sheet 31 and second metal sheet 32 insulated through an insulating layer 34 and is configured so that when electric power has been supplied from the power source, current flows through one of the first metal sheet 31 or second metal sheet 32 to the power transmission coil 2 and the current flowing through the power transmission coil 2is returned through the other of the first metal sheet 31 or second metal sheet 32 to the power source and configured so that the direction of the current flowing through the first metal sheet 31 and the direction of the current flowing through the second metal sheet 32 become opposite.
