Abstract
A memory card is disclosed which has a card body (2) having a concavity (9) formed at the forward end thereof in the inserting direction and in which terminals (5) are disposed and projections (10) are formed between the terminals (5) to prevent the terminals (5) from being touched or accessed from outside. A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.
