MOBILE TERMINAL DEVICE

摘要

When a key button (25a) is pressed, a second circuit substrate (24) and a circuit part (30) should be protected from an external stress by a box (28). A mobile terminal device has a first circuit substrate (23) in a case (11) and a second circuit substrate (24) in a case (12) and a shield member (26) is provided between the first circuit substrate (23) and the second circuit substrate (24). The shield member (26) includes a case (27) formed of an elastic member and a box (28) inserted into the space in a case (27). The case and the box are made into a unitary block and fixed to the first circuit substrate (23) and the second circuit substrate (24) with an engagement claws (27d, 27e).
