Then, whole forms transparent insulating film, by etching etc., the two ends in the y direction of cross part nesa coating 16c are exposed, thus form cross part/underlying insulation film 32.
Then, similarly, the formation of the nesa coating 14 and 16 beyond cross part nesa coating 16c and the formation of protection dielectric film 24 is carried out.
That is, the sensor one-piece type cover glass 10a shown in Fig. 4 (A) ~ 4 (C) have x direction extend the first nesa coating and y direction extend the second nesa coating and be arranged on the first nesa coating and the second nesa coating cross part two conducting films between and at above-mentioned first nesa coating and the transparent cross part/underlying insulation film including organic compounds between the second nesa coating and glass plate.
In other words; in the one-piece type cover glass of sensor shown in Fig. 1 (A) ~ 1 (D); not there is underlying insulation film in the below of the nesa coating of bridge; and cross part dielectric film extends to the first nesa coating beyond bridge and between the second nesa coating and glass plate, plays a role as underlying insulation film.
When the one-piece type cover glass 10 of the sensor shown in shop drawings 1 (A) ~ 1 (D), need to add the such operation of formation underlying insulation film.On the other hand, the sensor one-piece type cover glass 10a shown in Fig. 4 (A) ~ 4 (C) of present embodiment can manufacture with the process number identical with the one-piece type cover glass of sensor in the past when not increasing process number.In addition, underlying insulation film can be set between nesa coating and glass plate in most of region, the effect that the face intensity that therefore can also obtain the sensor cover 12b preventing glass plate 12 fully reduces.
On the other hand, the one-piece type cover glass 10 of the sensor shown in Fig. 1 (A) ~ 1 (D) also has underlying insulation film in the below of bridge, is therefore favourable in the intensity of glass plate 12.
Above, be illustrated in detail, but the present invention is not limited to above-mentioned example to the one-piece type cover glass of sensor of the present invention, without departing from the spirit and scope of the invention, can carry out various improvement, change, this is natural.
