Abstract
A portable information terminal according to the present invention uses a main board and a memory sheet. The main board has a complicated configuration. The memory sheet has silicon chips for memory. The memory sheet comprises a film-shaped circuit board and the silicon chips mounted on the film-shaped circuit board. A contact for the memory sheet is connected to a connecting terminal of the main board. This configuration allows the mounting of a large capacity of memory while keeping the thickness of the portable information terminal in a thin state. As a result, a portability-improved portable information terminal can be obtained in which a large capacity of memory was contained and miniaturization, thickness reduction and weight reduction were achieved.
