Abstract

The efficiency of a product cycle is considerably enhanced by avoiding loss from designing to production including member loss matching various sizes of touch sensor panels.
Unit sensor sheets having a square outer shape on which a multiple number of sense lines 21 as a multiple number of conductive wirings are arranged in parallel, are disposed in 3 row, 3 column. Each end of each of the multiple number of sense lines 21 as a multiple number of conductive wirings is sequentially matched one-to-one between unit sensor sheets, for example, between the sensor sheets 2 A and 2 B, or the sensor sheets 2 B and 2 C, and electrically connected with each other, and thereby the respective multiple number of sense lines 21 as a multiple number of conductive wirings are connected in a longitudinal direction thereof and are integrated, in the 3 row, 3 column of the unit sensor sheets 2 A- 2 I.
