Abstract:
1. A method of manufacturing a wiring board comprising an insulating substrate which includes a first and second regions adjacent to each other in one major surface, signal lines arrayed on the first region, and wiring patterns which is arrayed on the second region and each includes a first connection wiring line connecting the signal line to a signal input terminal, a second connection wiring line electrically disconnected from the signal line, and a third connection wiring line electrically disconnected from the signal line, the second and third connection wiring lines being connected to each other between each adjacent wiring patterns, and all of the signal lines being connected to the first connection wiring lines of the wiring patterns, comprising: forming each of the wiring patterns by a photolithography process, wherein, in the photolithography process, pattern exposure using a single photomask which includes a pattern having a shape corresponding to part of the wiring patterns is sequentially executed for all parts of the second region, and wherein forming the wiring patterns is carried out such that resistors which mutually connect the first to third connection wiring lines included in the same wiring pattern are formed on a third region in the major surface of the insulating substrate, the third region being adjacent to the first region via the second region, and wherein the method further comprises: cutting the insulating substrate at a boundary between the second and third regions to disconnect the first to third connection wiring lines included in the same wiring pattern from one another.
