[0007]However, since the back side substrate is a thin object with a thickness of about 0.2 to 3.0mm, when a glass plate is used for the back side substrate, if the conductive pin is pressed into the through-hole of the substrate on the back side, the possibility of cracks or cracks in the substrate on the back side is high due to the press-fitting
Also, when a glass plate is used for the back side substrate, the conductive pins cannot be pressed into the through holes of the back side substrate by ultrasonic melting, so the possibility of cracks or cracks on the back side substrate caused by the pressing cannot be reduced. sex

Abstract
A protection panel with a touch input function and a method for manufacturing the same are disclosed in which a thickness of a protection panel is reduced by using a glass plate as a rear substrate, and at the same time, a risk of generating crack or fracture in the rear substrate is suppressed, when a conductive pin is press-fitted into a through hole of the rear substrate. The protection panel with a touch input function includes: a front substrate (6) which has a resistive film (6A) formed on a rear face of the front substrate and whose rim portion (6E) is decorated; and a rear substrate (5) including at least a glass plate which has a resistive film (5A) on a front face of the rear substrate and whose rim portion has through holes (5a,5b) for electric conduction, which are connected so that the resistive films (5A,6A) are opposingly arranged with a predetermined gap, and electrodes (5D,6D) of the resistive films (5A,5B) are conductively connected to external terminals C through the through holes (5a,5b). In this protection panel, a conductive adhesive (10) is injected into the through hole (5a,5b), and a protection member (12) is provided between a conductive pin (11) inserted into the through hole (5a,5b) with the conductive adhesive (10) injected thereinto and an inner wall of the through hole (5a,5b).
Description
technical field [0001] The present invention relates to a protective panel with a touch input function and a manufacturing method thereof. The protective panel is configured by connecting a surface-side substrate and a rear-side substrate so that their respective resistive films face each other at a predetermined interval, and using a The hole electrically connects the electrode of the above-mentioned resistive film and the external terminal, wherein the above-mentioned surface-side substrate is formed with the above-mentioned resistive film on the back side, and the peripheral portion is decorated, and the above-mentioned back-side substrate includes at least a glass plate and is formed on the front side. The above-mentioned resistive film is formed, and a via hole for conducting electricity is formed in the peripheral portion. Background technique [0002] In some protective panels with a touch input function as described above, a conductive paste as a connecting agent is ...
