Power receiving system

A power receiving system that receives power supplied wirelessly to a power receiving circuit provided on a bottom portion of a vehicle, the power receiving system comprising:

• a power-receiving-side antenna coil unit including:
• a power-receiving-side antenna coil, which is a coil formed by wrapping a conductive wire around a reference axis, the power-receiving-side antenna coil being provided in the power receiving circuit, and being configured to receive power transmitted via a magnetic field, and
• a first shield member made of a magnetic material, the first shield member being arranged along a radial direction of the power-receiving-side antenna coil on a non-transmission direction side, which is a side opposite to a transmission direction side and which is one side along the reference axis, of the power-receiving-side antenna coil;
• and
• a second shield member made of a conductive material, the second shield member having a shape conforming to a recessed and protruding shape of a target region including a recessed portion that is recessed upward of a vehicle body bottom surface of the vehicle and being arranged in the target region,
• wherein the power-receiving-side antenna coil unit is arranged at a position overlapping with the recessed portion in a view in a direction along the reference axis.
