Method for Manufacturing Intermediate Member for Conductive Pattern Sheet Next, a method for manufacturing an intermediate member for a touch panel sensor sheet using such an intermediate member manufacturing apparatus 200 will be described.

First, a base material roll 132r formed by winding a long insulating base material 132 into a roll shape is prepared and installed on the base material supply shaft 202. Next, the base material supply shaft 202 is rotated, and the insulating base material 132 is fed from the base material roll 132r toward the base material transport path. The fed insulating base material 132r is conveyed toward the metal layer forming apparatus 206 while being supported by the feed roller 204.

In the first conductor manufacturing apparatus 206, the first conductors 41 and 46 are manufactured on one side surface 132a and the other side surface 132b of the insulating base material 132.

The conductors 41 are manufactured so as to be separated from each other, and a plurality of other side first conductors 46 are manufactured so as to be separated from each other on the other side surface 132b. The insulating base material 132 that has passed through the first conductor manufacturing device 206 is conveyed toward the second conductor manufacturing device 208 while being supported by the feed roller 204.

In the second conductor manufacturing apparatus 208, the second conductor is placed on one side surface 132a and the other side surface 132b of the insulating base material 132, around the first conductors 41, 46, and the first conductors 41, 46.

In the take-out conductor manufacturing apparatus 210, the take-out conductor is made on one side surface 132a and the other side surface 132b of the insulating base material 132. Specifically, the take-out conductor extends from the first conductors 41, 46 produced in the product regions P1, P2, P3 of each unit region U1, U2, U3 to the non-product regions M1, M2, M3. In addition, the take-out conductors provided corresponding to the first conductors 41 and 46 arranged in the product area of one unit area are arranged in the product area of another unit area adjacent to the one unit area.

Specifically, it is confirmed by conducting an electrical inspection whether each of the first conductors 41 is not broken and whether the first conductors 41 are electrically insulated from each other.

Alternatively, instead of cutting the entire non-product area M1, M2, M3 of the intermediate member 130 for the touch panel sensor sheet, as shown in FIG. 6, only a part of the non-product area M1, M2, M3 is removed. Inspections can also be carried out. In the example shown in FIG. 6, in the non-product areas M1, M2, M3 of the intermediate member 130 for the touch panel sensor sheet, the insulating group is formed by cutting out the portion where the connecting portion and the extension wirings 142a and 142b are connected. It is possible to break the connection of each conductor that should be originally electrically independent (insulated) on the material 132.

By combining the touch panel sensor 30 thus obtained with the display device 15, the input / output device 10 can be obtained. In this case, a part of the extension wirings 142a and 142b to which one end is connected to the terminal portions 44 and 49 remains in the touch panel sensor 30. More specifically, the touch panel sensor (conductor pattern sheet) 30 has a plurality of first conductors 41, 46 and one-sided take-out conductors electrically connected to the first conductors 41, 46, respectively. Each take-out conductor has a take-out wiring 43, 48 connected to each of the first conductors 41, 46 at one end thereof, a terminal portion 44, 49 connected to the other end of the take-out conductor 43, 48, and a terminal portion 44, Includes extension wires 142a, 142b extending between 49 and the edge 32e of the substrate 32. The extension wirings 142a and 142b are narrower than the terminal portions 44 and 49. In such a touch panel sensor (conductor pattern sheet) 30, the terminal portions 44 and 49 are separated from the edge portion 32e of the base material 32, and damage to the terminal portions 44 and 49 can be effectively prevented.

The protective films 80a and 80b are removed at any time before the touch panel sensor 30 is combined with the display device 15.

That is, the first conductor, the second conductor, and the take-out conductor independently arranged in the plurality of unit regions form a continuous conductor pattern as a whole. As a result, the potential in the pattern can be made uniform, and it is effectively avoided that the charge amount of some of the conductors increases and discharges, and the conductors are destroyed.

Further, during the production of the intermediate member for the touch panel sensor sheet, the pattern of the conductor produced on the insulating base material 132 is brought into contact with the conductive static elimination rollers 212a and 212b connected to the ground, thereby forming the inside of the pattern.
