[0053] In this embodiment, a touch panel device is taken as an example of an electronic device, and a waterproof structure of the touch panel device will be described. The touch panel device is used as an input device used in combination with various display panels, such as a portable information terminal device, a display for a computer, a car navigation device, an ATM, and a ticket vending machine.
[0054] like figure 1 As shown, the touch panel device 10 has a display panel 12 such as a liquid crystal display panel or an EL display panel, and a touch panel 14 for performing input operations, and has a housing 16 formed of resin or the like for accommodating the display panel 12 and the touch panel 14 .
[0055] Around the touch panel device 10, a decorative film 17 processed by the TOM process method (Three Dimension Overlay Method) described below is closely adhered to the entire periphery. Since the portion of the decorative film that is not in close contact with the su...

[0084] In this embodiment, as an electronic device, take a camera module as an example, use Figure 11 to Figure 13 The waterproof structure of the camera module will be described. Figure 11 is a perspective view showing the appearance of the camera module 30 of this embodiment, Figure 12 Yes Figure 11 The central longitudinal sectional view of the shown camera module 30, Figure 13 It is an exploded view showing only the first case 32 and the second case 33 .
[0085] The camera module 30 is mainly used for being attached to the rear or the left and right sides of the vehicle body of an automobile (not shown), and is mainly used for grasping the situation of a range forming a blind spot from the driver's seat of the automobile. In addition, by installing the camera modules 30 on the rear part and the left and right side parts of the vehicle body, and by processing and synthesizing the images obtained from the four camera modules 30, it is also possible to virtually cons...

[0106]In this embodiment, a connector is taken as an example to describe the waterproof structure of the connector. A card connector is used as an example for illustration, but other types of connectors are possible.
[0107] like Figure 14 As shown, the card connector 70 has a tray 76 accommodating a SIM card 78 and a case 75 capable of inserting and ejecting the tray 76 accommodating a SIM card. A plurality of hole portions 75 a are provided on the surface of the case 75 . A decorative film 77 processed by the TOM engineering method described in the first embodiment is closely attached to the periphery of the card connector 70 except for the opening 71 . Since the TOM engineering method used in this embodiment differs only in that the card connector 70 is used as a base material, description thereof will be omitted.
[0108] The decorative film 77 uses polyethylene terephthalate, but as long as it is thermoplastic, other materials can be used, for example, polybutylene t...
