PROBLEM TO BE SOLVED: To provide a rigid-board interconnection structure which gives a long bending life free from stress concentration in flexible boards when the flexible boards are bent. SOLUTION: First and second flexible boards 30, 40 are mutually glued with an adhesion layer 50 in the vicinity of interconnection portions of first and second rigid boards 10, 20 in such a way that the spacing between the first and second flexible boards 30, 40 is narrower than the thickness of the first and second rigid boards.
