When the user presses down the key button 25a with the finger 40 as shown in FIG. 7B from the state shown in FIG. 7A, the stress 45 generated is propagated to the first circuit board 23. However, the box body 28 of the shield member 26 disposed below the box body 28 resists the stress caused by the stress 45 and minimizes the deformation. The top surface portion 28b of the box body 28 formed by the sheet metal member has a stress of 45 when the pressing operation is performed.
A protective structure is formed that has a rigidity that can repel each other and that is supported by the entire box body 28 so that the internal circuit component 30 and the joint portion 42 are not distorted.

Further, the stress 45 acting downward when the key button 25a is depressed is due to the contact portions 31a, 3a of the box 28.
It is propagated from 2a to the second circuit board 24. However, since the receiving rib 43 of the lower housing 22 is disposed vertically downward of the positions of the contact portions 31a and 32a, that is, the position of the frame body 27 of the shield member 26, the receiving ribs 43 contact the contact portion 31a. The second circuit board 24 between the contact portions 32a has a structure such that deformation or distortion does not occur, and a further protective structure is realized.
