Abstract

A card-shaped electronic device is used with an electronic apparatus. A rectangular flat box-like main-body of the card-shaped electronic device can be inserted into and taken out of the electronic apparatus in a given insertion direction. The main-body has a pair of lateral sides extending in the insertion direction. A pair of shield plates fixed to the main-body cover the upper and lower surfaces of the main-body. A conductive portion is arranged on the lateral side of the main-body and is electrically connected to the shield plates, for conducting the shield plates with the electronic apparatus when the main-body is loaded in the electronic apparatus.
