A portable telephone set includes a main section thereof, an IC card, and a battery pack, which are removably connected to each other. The battery pack has an L-shaped rib to provide a slot in which the IC card is inserted. When the IC card is inserted in the slot, a side surface of the IC card is brought into contact with a side surface of the battery pack to be held therein in a unified form. In the combined state, a hook section of the battery pack is engaged with an engaging section of the main section. When the battery pack is pushed downward, a depressed portion of the battery pack is engaged with a lock member of the main section so as to fixedly attach the battery pack onto the main section. The IC card is pushed by the battery pack to be brought into contact with a connector of the main section so as to establish a stable connection therebetween. There is provided a small-sized, low-cost portable telephone set having improved operability of IC card installation and removal.
