Document Type and Number:
WIPO Patent Application WO/2012/053089
Kind Code:
A1
Abstract:
In the present invention, in order to increase forward sensitivity of a coil having longitudinal antenna directivity, a metal object is placed near the rear of the coil and the coil and the metal object are retained in a bobbin case. The bobbin case has a substrate mounting surface which is a surface fixed to the substrate surface of an electronic device and which is a surface parallel or substantially parallel to the direction of antenna directivity of the coil. When the present invention is mounted in the substrate surface of the electronic device, it is possible to form a sensitive region which extends in a direction parallel to the substrate surface and with high sensitivity in one direction.
