PROBLEM TO BE SOLVED: To provide a wiring board that prevents a flexible circuit connector provided on the wiring board from floating and that does not scratch the outer surface of a paper substrate.SOLUTION: A wiring board 70 includes a paper substrate 30 and wiring 18A. The paper substrate 30 includes at least a first substrate 30b1, a second substrate 30b2, a first side plate 30c1, and a second side plate 30c2. A flexible circuit connector 80B is provided at a bent portion 64A between the first substrate 30b1 and second substrate 30b2. The second side plate 30c2 is provided with an engaging piece 111 for holding an end of the flexible circuit connector 80B and an opening 112 is formed at the base end of the engaging piece 111.SELECTED DRAWING: Figure 5ACOPYRIGHT: (C)2020,JPO&INPIT【課題】配線基板に設けられたフレキシブル回路コネクタの浮き上がりを防止し、紙基板の外面を傷を付けない。【解決手段】配線基板７０は紙基板３０と、配線１８Ａとを備える。紙基板３０は少なくとも第１基板３０ｂ１と、第２基板３０ｂ２と、第１側板３０ｃ１と、第２側板３０ｃ２とを有する。第１基板３０ｂ１と第２基板３０ｂ２との間の折曲部６４Ａにフレキシブル回路コネクタ８０Ｂが設けられている。第２側板３０ｃ２にフレキシブル回路コネクタ８０Ｂの端部を押える係止片１１１が設けられ、係止片１１１の基端に開口１１２が形成されている。【選択図】図５Ａ
