PROBLEM TO BE SOLVED: To solve the problem of conventionally requiring a mechanism for shielding a contact part by GND, due to having influence on electric equipment, when a radiation field is generated as a result, since a reflected wave by mismatching of impedance is generated when a high speed signal passes through the contact part between printed circuit boards. SOLUTION: This electric board connection structure is provided for positioning and connecting a first electric board 1 and a second electric board 2. Predetermined first patterns 1h, 1i and 1j are arranged on the first electric board, and predetermined second patterns 2h, 2i and 2j are arranged on the second electric board. When the first patterns and the second patterns are formed in a radial shape, the first patterns and the second patterns are covered with a screw, and both the electric boards are connected by fastening torque by being co-fastened to a board metallic chassis part being the GND, and a connection part is shielded by a machine screw and a chassis.
