PROBLEM TO BE SOLVED: To provide a connection structure suitable for increasing of connection parts and narrowing of pitches between circuit boards without using wire bonding in the connection structure of the circuit board where the circuit boards are electrically connected. SOLUTION: In the connection structure of the circuit board where circuit boards 10 and 20 are electrically connected, a convex and concave part 13 with a convex and concave shape is formed at the end of a first circuit board 10, a convex and concave part 23 with a convex and concave shape corresponding to the convex and concave part 13 of the first circuit board 10 is formed at the end of a second circuit board 20, the convex and concave part 13 of the first circuit board 10 and the convex and concave part 23 of the second circuit board 20 are close-fitted so as to be engaged with each other, and the both circuit boards 10 and 20 are electrically connected via a conductive connecting member 50 at a portion where the first circuit board 10 and the second circuit board 20 are close-fitted.
