[0032] "Modification 1"
[0033] Although the conductive region can be divided, the difference between the area of the conductive region 5 in the first section P1 and the area of the conductive region 5 in the second section P2 is large in the extending direction of the wiring, and the electrical characteristics are not balanced. Therefore, if Figure 2A As shown, the laser trimming is performed by the third trimming line L3 for adjusting the area of the conductive region parallel to the trimming line L2. In this case, the position of the trimming line L3 is determined so that the areas of one side and the other side of the conductive region divided by the trimming line L3 are as equal as possible. Thereby, the areas of the conductive regions are equalized, and fluctuations in coupling capacitance in the extending direction of the wiring can be suppressed. In addition, in Figure 2A In , the parts to be wiring are shaded.

[0034] "Modification 2"
[0035] Such as Figure 2B As shown, in the first section P1 of the trimming line L1 , the trimming line L2 for wiring width adjustment is provided to cross the conductive region 5 . As a result, the area of the conductive region 5 can be made smaller, and the coupling capacitance between the conductive region 5 and other wirings can be made smaller.

[0036] "Modification 3"
[0037] Such as image 3As shown, the present invention can be applied even to the case where there are conductive regions 5 a and 5 b as the tolerance margin 4 on both sides of the wiring region 2 . The first trimming line L1a, the second trimming line L2a, and the third trimming line L3a are arranged on one conductive region 5a. The first trimming line L1b, the second trimming line L2b, and the third trimming line L3b are arranged on the other conductive region 5b. A first section including wiring of a first width and a second section including wiring of a second width larger than the first width crossing the conductive regions 5a and 5b in the width direction are formed by the first trimming lines L1a and L1b. . The second trimming lines L2a and L2b intersect the first trimming lines L1a and L1b respectively in the second section so that the width of the wiring in the second section is smaller than the second width. The area of the conductive ...
