In a protective panel with a touch input function of an electronic apparatus display window, with a built-in antenna being placed on a back side thereof, an upper electrode sheet and a lower electrode panel that constitute the protective panel with a touch input function are respectively provided with radio-wave transmitting sections with no conductor formed therein, within a frame area to be covered with a decorative layer, in association with the built-in antenna, and with respect to all the portion or most of the portion of a border relative to the conductor of the radio-wave transmitting section on the upper electrode sheet side, since a paste layer, used for bonding the upper electrode sheet to the lower electrode panel at peripheral edge portions thereof, is provided with a through hole in a manner so as to overlap with, at least, an area near the inside of the border, with air inside the through hole being allowed to flow in or flow out through an air bent.

Protective panel with touch input function superior in surface flatness and electronic apparatus having the protective panel

A protective panel having touch panel function is used for protecting a front surface of a display device that is disposed so as to be visually recognized from outside, and the protective panel is fitted in a panel fitting part of a casing provided with an opening such that an outer surface of the protective panel forms a flat plane identical with that of the casing with no gap formed therebetween. The protective panel includes: an upper electrode sheet having a decorative layer and upper electrodes provided thereon; and a lower electrode sheet having lower electrodes provided on an upper surface thereof, and the upper electrode sheet and the lower electrode sheet are disposed such that the respective electrodes thereof face with each other. On a lower surface of the upper electrode sheet, at a non-electrode part not provided with the upper electrodes, there is provided a height difference adjustment part that has a thickness substantially equal to each of those of the upper electrodes, and the height difference adjustment part is provided such that short circuit is prevented with the upper electrodes as well as with the lower electrodes.

Protective panel having touch panel function

There are included a protection panel main body configured by a transparent plate, a lower electrode sheet laminated onto an upper surface of the protection panel main body, an upper electrode sheet bonded to the lower electrode sheet at peripheral edges thereof with a gap being formed between electrodes, a decorative sheet laminated onto an upper surface of the upper electrode sheet, and an FPC that has an end inserted between the lower electrode sheet and the upper electrode sheet and is connected by thermal compression bonding to output ends of an upper circuit and a lower circuit. Further, the protection panel main body is provided with a thermal compression head inserting space at a portion corresponding to a portion bonded with the FPC by thermal compression so that a thermal compression heater is allowed to be brought closer to the lower electrode sheet.
