Problems solved by technology

In this case, in the state where the transparent conductive film is exposed, the transparent conductive film is easily damaged, and it is also easily affected by changes in the surrounding environment such as temperature and humidity.
Therefore, due to these reasons, the surface resistance value of the transparent conductive film, that is, the characteristics (antenna characteristics, etc.) of the touch switch change, and there is a possibility of malfunction.

Abstract

The invention provides an intermediate for a contact switch with mode of electrostatic capacity, capable of implementing reduced cost and improved reliability. The intermediate comprises: an internal mold film forming a transparent conductive film (33) thereon by a base film (31); a plate-like panel part (2) formed by carrying out internal mold shaping; and a transparent conductive film (33) which is configured on the panel part (2) by internal mold shaping and configured within the panel part (2) so as to locate on central part at thickness direction of the panel part (2).

Description

technical field [0001] The present invention relates to a capacitive touch switch intermediate having a panel portion and a transparent conductive film provided on the panel portion, and a method for producing the touch switch intermediate. Background technique [0002] In recent years, many electronic devices, such as portable information terminals and automatic teller machines, have been equipped with touch-type operation parts that allow input by touching (touching) with fingertips. The touch operation unit is formed by providing a transparent conductive film on one surface of a light-transmitting panel unit, and is formed by mounting a touch switch (touch panel) on a display such as a CRT or LCD. In addition, the capacitive touch switch that detects the presence or absence of contact or the contact position according to the change in capacitance is mounted as follows so that the surface on which the transparent conductive film is placed is on the display side, and the su...
