Patent ID: 7214887

Claim:
An electronic circuit connecting structure comprising: a circuit board with a plurality of first connection lands, which are conductor patterns, formed on a surface thereof; and a flexible board arranged opposite to the circuit board, the flexible board including: a plurality of second connection lands arranged opposite to the respective plurality of first connection lands of the circuit board, a width of each second connection land being narrower than a width of each first connection land; and an insulating layer formed so as to surround a part of an outer periphery of each of the second connection lands without completely surrounding each outer periphery, the insulating layer including a plurality of insulating strips, each insulating strip disposed between adjacent second connection lands and provided such that a space is formed between the outer periphery of each of the second connection lands and each of the insulating strips and such that the first connection lands and the insulating strips touch, wherein each of the first connection lands and each of the second connection lands are bonded to each other via one of a respective plurality of bonding members, and a thickness of the insulating layer is greater than a total thickness of the first connection lands and the second connection lands.
