PROBLEM TO BE SOLVED: To reduce a connection part of two conductive patterns, when employing a structure for connecting the two conductive patterns through an insulation film. SOLUTION: A first conductive layer 11, a layer insulation film 12 and a second conductive layer 13 are laminated sequentially, and the first conductive layer 11 is connected to the second conductive layer 13 through an opening 12a of the layer insulation film 12. In the opening part 12a of the layer insulation film 12, the first conductive layer 11 and the second conductive layer 13 are formed to identical configuration, and the part of the same configuration becomes a connection part 14. The first conductive layer 11 and the second conductive layer 13 are interconnected in the connection part 14. The opening 12a of the layer insulation film 12 is sufficiently larger than the connection part 14. Therefore, a margin for aligning the first conductive layer 11 to the opening 12a and a margin for aligning the second conductive layer 13 to the opening 12a become unnecessary.
