PROBLEM TO BE SOLVED: To provide a circuit board that secures an excellent conductive connection state by eliminating a contact failure between terminals during connection, makes pitches of the terminals fine and saves the space of a printed board, and enables parts as contacts between the terminals to be easily determined, and to provide a connection structure and a method of manufacturing the connection structure. SOLUTION: The circuit board includes a base substrate 30 and first terminals 40 provided on the base substrate 30 and having a multi-stage shape comprising three or more stages, and the first terminals 40 each include a first stage 41 which is disposed on the base substrate 30, a second stage 42 which is disposed on the first stage 41 and has a smaller area than the first stage 41 in plan view, and a third stage 43 which is disposed on the second stage 42 and has a smaller area than the second stage 42 in plan view.
