PROBLEM TO BE SOLVED: To provide a power transmission relay device which allows for efficient power supply from a power transmission coil to a power reception coil included in an electronic product, by interposing between the power transmission coil and power reception coil, even though the distance therebetween is far away, when charging the electronic product.SOLUTION: In a power transmission relay device, a mobile device 1 moving between a power transmission coil 7 and a power reception coil 8, and the relay coil body 2b of a relay coil l2 fixed to the mobile device 1 are arranged so that a distance allowing appropriate resonance with a magnetic field generated in the power transmission coil body 7b of the power transmission coil 7 is ensured for any position of the surface. When a current flows through the relay coil body 2b of a relay coil l2, and a magnetic field generated by the current and the power reception coil body 8b of the power reception coil 8 resonate, power is supplied efficiently from the power transmission coil body 7b to the power reception coil body 8b.SELECTED DRAWING: Figure 1
