Abstract One embodiment is intended to provide a flexible circuit board with enhanced reliability, a COF module, and an electronic device comprising the same. A flexible circuit board according to one embodiment comprises: a substrate; a first wiring pattern layer disposed on an upper surface of the substrate; a first plating layer disposed on the first wiring pattern layer and including a first open area; and a first protective layer which comes into contact with a part of the first wiring pattern layer, a part of the first plating layer, and a part of the substrate. The first protective layer includes: a first overlapping region in which the first plating layer and the first protective layer are in contact with each other at one side of the first open region; and a second overlapping region in which the first plating layer and the first protective layer are in contact with each other at the other side of the first open region, wherein a width of the first overlapping region is different from a width of the second overlapping region, and each of the widths of the first and second overlapping regions is greater than a thickness of the first plating layer. 실시 예에 따른 연성 회로 기판은 기판; 상기 기판의 상면 상에 배치된 제1 배선 패턴층; 상기 제1 배선 패턴층 상에 배치되고, 제1 오픈 영역을 포함하는 제1 도금층; 및 상기 제1 배선 패턴층의 일부, 상기 제1 도금층의 일부 및 상기 기판의 일부와 접촉하는 제1 보호층;을 포함하고, 상기 제1 보호층은, 상기 제1 오픈 영역의 일측에서 상기 제1 도금층과 상기 제1 보호층이 서로 접촉하는 제1 중첩 영역; 및 상기 제1 오픈 영역의 타측에서 상기 제1 도금층과 상기 제1 보호층이 서로 접촉하는 제2 중첩 영역을 포함하고, 상기 제1 중첩 영역의 폭은 상기 제2 중첩 영역의 폭과 다르고, 상기 제1 및 제2 중첩 영역의 각각의 폭은 상기 제1 도금층의 두께보다 크다.
