A card-type apparatus includes a circuit substrate and a card-type case for accommodating the circuit substrate including a flat portion disposed opposite to the circuit substrate with a gap between the circuit substrate and the flat portion. A memory card accommodating space, provided between the flat portion of the card-type case and the circuit substrate, is capable of detachably accommodating the memory card inserted from a memory card slot along the circuit substrate surface. A terminal is provided on a region of the circuit substrate in the memory card accommodating space. A plate section for adjusting the gap is provided on the flat portion on the side of the memory card accommodating space. On the plate section, a protrusion is provided so as to increase the contact pressure between the memory card and the terminal by pressing the memory card stored in the memory card accommodating space against the terminal.
