1. A memory card socket structure, comprising:
a case having a card accommodating portion for receiving a thin plate-shaped memory card; and
a contact block having contact terminals to be brought into contact with terminals of the memory card,
wherein the case has a cover shell and a base shell both formed of metal plates, and the cover shell and the base shell are welded to each other by a laser welding, and
wherein the base shell has a substantially rectangular plate-shaped base and a pair of sidewalls extending from two opposite ends of the base approximately in a perpendicular manner, and the cover shell is formed in a substantially rectangular plate shape, and edges of the sidewalls of the base shell and edges of the cover shell corresponding thereto are joined by the laser welding at a state in which the cover shell is mounted on the sidewalls.
2. The socket structure of claim 1 , wherein one or more cutout portion is formed at the edges of the cover shell to partially expose the edges of the sidewalls of the shell therethrough.
3. The socket structure of claim 2 , wherein marks are provided on the edges of the sidewalls of the base shell and the marks are exposed through the cutout portion.
