Abstract: There is provided a PC card-type wireless LAN card including a metal cover in which lowering of throughput of data transmission is prevented. In a card-type wireless communication device (wireless LAN card) in which a printed board assembly including an antenna, an RF (radio frequency) circuit part (wireless circuit part), a baseband circuit part, and a connector for connection with an information terminal device is fixed to a frame made of synthetic resin, and is covered with a top cover made of metal and a bottom cover except for the portion of the antenna, a shield case made of metal covering the RF circuit part and electrically connected to a ground pattern and the top cover made of metal are brought into contact with each other in a wide range through a metal conductor worked into a shape having elasticity.
