Abstract
A connection structure and method of circuit boards including electronic parts thereon and a flexible cable for coupling the circuit boards. A first circuit board mounting electronic parts such as light detector elements and the like in an image sensor and a conductive pattern for connecting an image signal of the light detector elements to an external circuit and a second circuit board including amplifying ICs and a conductive pattern connected thereto are mutually laminated. The first circuit board is formed with a slot and a flexible bridging conductor is inserted into the slot. The flexible cable having a conductive pattern at its end is laminated on the laminated circuit boards so as to correspond to the conductive patterns. The flexible cable and the laminated circuit boards are closely fixed by a fixing plate to perform an electrical connection between the electronic parts of the circuit boards and between the electronic parts and the flexible cable at the same time without using soldering.
