[0024] In the present embodiment, as shown in FIG. 2, the plurality of clips 10 are attached to the four corners of the frame portion 9. Correspondingly, as shown in FIGS. 3, 5(A), and 5(B), the case 4 has a plurality (four in the present embodiment) of mounting holes 12 penetrating the accommodation recess 8 at each mounting position of the plurality of clips 10.

[0025] Note that the number and arrangement of the clips 10 are not limited to the above-described configuration, and can be appropriately changed according to the size of the touch panel 3 and the like.

[0026] The clip 10 can sandwich the frame portion 9 between the front elastic piece 10a and the back elastic piece 10b at the position where the mounting hole 12 is formed. Further, the front elastic piece 10a is located on the back side of the frame portion 9, and the back elastic piece 10b is located on the back side of the frame portion 9.

[0027] As shown in FIGS. 5(A) and 5(B), the case 4 has a positioning recess 13 recessed in a shape corresponding to the front elastic piece 10a on the front side of the frame portion 9 so that the front side of the frame portion 9 and the front side of the front elastic piece 10a are flush.

[0028] The clip 10 is held in a state where the front elastic piece 10a is positioned in the positioning recess 13 while sandwiching the frame portion 9 between the front elastic piece 10a and the back elastic piece 10b.

[0029] Also, as shown in FIGS. 6(A) and 6(B), the clip 10 has a locking hole 14 that penetrates the back elastic piece 10b. On the other hand, the case 4 has a locking claw 15 that protrudes from the back side of the frame portion 9.

[0030] In the present embodiment, the locking hole 14 is rectangularly open in a plan view. A pair of arm portions 10d are provided on both sides of the back elastic piece 10b sandwiching the locking hole 14. Also, the distal ends of the pair of arm portions 10d are connected via a connecting portion 10e.
