<p>A power transmission coil in which heat generation by a magnetic shield itself can be suppressed as far as possible is provided.</p><p>A power transmission coil is configured by: a coil (1) wound in a plane; and a magnetic shield member (2) disposed on the rear surface of the coil (1). A most part, e.g. 65% or more, and preferably 70% or more of the area of the surface of the magnetic shield member (2) on which the coil is disposed is covered by the coil (1). In this case, the magnetic shield member (2) is formed in a rectangular shape, and the coil (1) is formed in a rectangular shape similar to the magnetic shield member (2).
