A substrate includes fine lines. The fine lines are obtained according to a fine-line forming process, which includes a process of projecting light from above the substrate onto predetermined regions on a photosensitive material provided on the substrate and a developing process after the light projection process. A narrow-width portion is provided at an end portion of each of the fine lines in a longitudinal direction of the fine line. The width of the narrow-width portion is smaller than the width of a portion adjacent to the narrow-width portion.

What is claimed is: 1. A method of manufacturing a substrate having a fine line on a substrate face, said method comprising: a fine-line forming step of forming the fine line on the substrate face, wherein an end portion of the fine line in a longitudinal direction is divided into a plurality of disjoined narrow width portions, and the fine line is formed so that a width of the disjoined narrow-width portions in a parallel direction to the substrate face is smaller than a width of a portion of the fine line adjacent to the fine line end portion divided into the plurality of disjoined narrow-width portions, and in a section of the fine line cut in the direction of a normal line on the face forming the fine line on the substrate, the section comprises a part which is away from the substrate-side-end of the section, and a length of a part of the section in the parallel direction to the substrate face is longer than a length of the substrate-side-end of the section in the parallel direction to the substrate face with sides extending diagonally outward from the substrate face, said fine-line forming step comprising: (i) a step of providing a photosensitive material onto the substrate; (ii) a step of projecting light from above the substrate onto a predetermined region on the photosensitive material; and (iii) a developing step after said step of projecting light. 2. A method according to claim 1, wherein the fine-line is a wire connected to a device.
