CARD-TYPE ELECTRONIC CIRCUIT MODULE

摘要

An SD card (1) includes a card-shaped housing (4) which is formed by assembling insulating upper and lower covers (2 and 3), and a circuit board (5) which is accommodated in the housing (4). The circuit board (5) extends along an inner wall (2a) of the upper cover (2). Terminal electrodes (6) are fixed near one side end of the lower cover (3) by insert molding and are exposed to the outside, and reinforcing ribs (3d) configured to make contact with the circuit board (5) are formed thereon. Wiring patterns are formed on the circuit board (5), and electronic components (8 and 8a) are mounted on a principal surface (5a). Elastic pieces (9) which extend from the terminal electrodes (6) to the inside of the housing (4) are in elastic-contact with connecting land portions (7) of the wiring patterns disposed at one end of the principal surface (5a).
