PROBLEM TO BE SOLVED: To solve a problem that is apt to occur in high-speed signal transmission due to deterioration in electric characteristic by a connector or cable when printed circuit boards are connected to each other through the connector or cable, in a structure where the two printed circuit boards are mechanically and electrically connected to each other, and to solve a problem of an increase in cost by the connector or cable. SOLUTION: A connection structure is achieved which has excellent electric characteristics for high-speed signal transmission and is reduced in cost using neither the connector nor the cable by: providing electrode terminals for power supply and a plurality of signals at a surface side part of one board; providing an oblong hole having electrode terminals corresponding to the power supply and the plurality of signals to an internal wall of the other board; mechanically connecting the board provided with the electrode terminal at the side part by inserting the board into the oblong hole of the other board which has the electrode terminals; and electrically connecting the electrode terminals by pressing and bringing them into contact or soldering them.
