Abstract:
[Problem] To expand the communication range of a loop antenna mounted on an electronic device in a main surface direction of the electronic device. [Solution] This electronic device cover is mounted on an electronic device having a first loop antenna that has a first loop portion and a first magnetic flux penetrating region provided inside the first loop portion and allowing magnetic flux to pass through the electronic device in a thickness direction. The electronic device cover is equipped a second loop antenna having a second loop portion at least partially opposed to the first loop portion in the thickness direction and magnetically coupled to the first loop antenna, a second magnetic flux penetrating region provided inside the second loop portion and allowing magnetic flux to pass through in the thickness direction, and a third loop portion that is continuous with the second loop portion and not opposed to the first loop portion or the first magnetic flux penetrating region in the thickness direction and that extends in a main surface direction of the electronic device perpendicular to the thickness direction.
