Abstract:
An interconnection structure comprising:a first printed circuit board including an insulating substrate made of a thermoplastic resin and a first board conductive pattern with a land; a second printed circuit board overlapped with the first printed circuit board, and including a second board conductive pattern with a land, wherein the land of the second board conductive pattern is parallel with the land of the first board conductive pattern; and an interconnection portion that electrically interconnects the land of the first board conductive pattern and the land of the second board conductive pattern, wherein a part of the thermoplastic resin constituting the insulating substrate of the first printed circuit board is deformed such that the thermoplastic resin of the first printed circuit board adheres to a surface of the second printed circuit board and to a side surface of the interconnection portion seal the interconnection portion.
