A memory card adapted to be removably loaded into electronic equipment, comprising:
- a contact pattern for exchanging information with an external equipment;
- an electrically conductive card-shaped case having an opening in a surface thereof at a position facing a position where said contact pattern is located;
- a shutter member for opening and closing said opening
- a memory element provided in said case and connected to said contact pattern for exchanging information with an external equipment;
- a printed circuit board provided in said case for making an electrical connection with said contact pattern and said memory element;
- and
- means provided in said case for making an electrical connection with said case and said printed circuit board to ground, static electricity being conducted to said printed circuit board through said case and said electrical connection means by closing said shutter member when said case is in a non-operative status unloaded from said external equipment, to prevent damage to said memory element due to said static electricity.
