CONNECTING STRUCTURE OF PRINTED WIRING BOARD, WIRING BOARD CONNECTOR AND ELECTRONIC DEVICE

PROBLEM TO BE SOLVED: To provide a connecting structure of a printed wiring board, a wiring board connector and an electronic device capable of preventing stress and deformation from concentrating on a peripheral edge portion of a connection region when an anisotropic conductive adhesive is used to connect two or more printed wiring boards.SOLUTION: A connecting structure of a printed wiring board in which two or more printed wiring boards are connected, includes: a first printed wiring board having a first connection region in which a cover layer is cut out so that a first connection electrode portion is exposed; and a second printed wiring board having a second connection region in which a cover layer is cut out so that a second connection electrode portion is exposed. In the structure, the first connection region and the second connection region are adhered through an anisotropic conductive adhesive, while the first connection electrode portion and the second connection electrode portion are conducted, and at least one of the first printed wiring board and the second printed wiring board is a flexible printed wiring board, and an edge portion of the cover layer on the flexible printed wiring board is cut out into a concavo-convex shape so as to form the connection region.
