PURPOSE:To improve ability to measure connection resistance between connecting parts of a circuit board and check a misregistration in circuit board connection, and to prevent disconnection of a circuit connection terminal. CONSTITUTION:Connection resistance between a connection terminal 1bbb and a connection terminal 2bb is measured using measurement terminals 1bba and 2ba. A misregistration between boards changes the connection area of the connection terminals 1bbb and 2bb, thus changing the connection resistance value. By measuring the resistance value using the measurement terminals 1bba and 2ba, it is possible to detect generation of a misregistration between a flexible board l and a printed board 2. |
