PROBLEM TO BE SOLVED: To provide a method of manufacturing an electronic component wiring board which is capable of preventing a short circuit from occurring between wiring patterns formed by etching or screen printing. SOLUTION: A circuit pattern is composed of wiring patterns 19 provided in array, a common wire 26 is provided to either of the wiring patterns 19, and the wiring patterns 19 are set independent of each other at a joint between the wiring pattern and the common wire 26. The circuit pattern is formed by etching in a method of manufacturing an electronic component wiring board 10, where a part 19a corresponding to the wiring pattern 19 is provided to a pattern mask 17 used for forming an etching resist film 18 utilized in an etching process, and a corresponding enlarged space 27 which furthermore enlarges a space 25 formed between the wiring patterns 19 is provided to the corner of the pattern mask 17 where a part 26a corresponding to the common wire 26 and a part 19a corresponding to the wiring pattern 19 are connected together.
