Claims

[Scope of claims for utility model registration] (1) In flexible printed wiring boards,
A bent part having a check land is provided on both sides of the communication part between the own wiring boards or with another electric circuit device, and when the bending part is bent, the check land is located on the side where the wiring pattern of the communication part is formed. A flexible printed wiring board featuring the following features. (2) In flexible printed wiring boards,
A check land is provided at a predetermined position of a connecting part between the own wiring boards or with another electric circuit device and a bent part provided in the connecting part,
A flexible printed wiring board characterized in that when the bent portion is bent, the check lands overlap each other and are located on opposing surfaces. (3) In flexible printed wiring boards,
1. A flexible printed wiring board, characterized in that a check land is provided at a connecting part between its own wiring boards or with another electric circuit device, and the check land is located on the inside when the connecting part is bent.
