A mobile terminal device of the present invention consists of a key side housing 20 having operation buttons et alia and a display side housing (not shown) having a liquid crystal display module. The key side housing 20 and the display side housing are coupled by a hinge device 8a to be folded free. The key side housing 20 consists of an upper case 1, a lower case 8 and a printed circuit board 6. The upper case 1 and the lower case 8 are engaged to each other to be opened or closed, and fastened to each other with screws 10 passing through the printed circuit board 6. The external connection terminal fixing structure of the mobile terminal device consists of external connection terminals 7 which is fixed to the printed circuit board 6 and charge terminals 4 overlapped with the external connection terminals 7. And the charge terminals 4 have a thickness enough to bridge the gap between the external connection terminals 7 fixed to the printed circuit board 6 and the upper case 1. By bridging the gap with the charge terminals 4, when the external connector 11 is connected to one of external connection terminals 7, a motion of the external connector 11 is transmitted to the printed circuit board 6 via the charge terminals 4, the upper case 1, and the lower case 8. By transmitting this motion from the external connection terminals 7 to the printed circuit board 6, the force of joining the solder joint portion and an electric conduction pattern which fixes the external connection terminals 7 is absorbable. <IMAGE> |
