An antenna device (100, 200) for non-contact power transmission is provided with: an antenna coil (10) which is mounted on a non-contact power transmission device capable of transmitting power in a non-contact manner and which is formed by winding a conductive member; multiple plate-like members (21, 22, 23, 24) which contain metal and which are disposed in the periphery of the antenna coil along the radial direction of the antenna coil; and a storage case (30) which contains metal and which stores the antenna coil and the plate-like members. The plate-like members are arranged such that the plate surfaces thereof intersect with a direction in which the conductive member configuring the antenna coil extends. It is possible to improve the power transmission efficiency while observing radio wave protection guidelines with the aforementioned antenna device for non-contact power transmission. |
