PURPOSE: To reduce the number of parts to simplify the structure and to mount parts with a high density to reduce the thickness of a device by using a supporting and pressing member constituted as one body to support and press parts.

CONSTITUTION: A supporting metal fitting 18 as the supporting and pressing member where conventional supporting plate and a retaining metal fitting are constituted as one body is used to not only support a coordinate input device but also press a RAM 4h, where an IC 4d is mounted on a film 4c, to a common terminal part 4a and press the common terminal part 4a. Thus, the number of parts is reduced by unifying two members to reduce the cost, and the peripheral structure of the common terminal part 4a which has a high density and trends to complication is simplified, and parts are mounted with a higher density to reduce the thickness.
