PROBLEM TO BE SOLVED: To provide a ground connection structure being capable of demonstrating sufficient noise-reduction effect while thinning a base member, being capable of preventing the malfunction of a signal transmission, of preventing a seasonable deterioration, and of reducing a cost. SOLUTION: In the ground connection structure, a circuit board 4 mounted on the base member 2 is grounded to the base member 2. The ground connection structure has an upper member 2U and a lower member 2L constituting the base member 2, a ground pattern 17 being formed to the circuit board 4 along the longitudinal direction of the circuit board, a spring housing 18 being formed to the upper member 2U and/or the lower member 2L in response to the ground pattern 17, and a spring 19 being housed in the spring housing 18 and being capable of being connected to the spring housing 18 and the ground pattern 17 at multipoints. In the ground connection structure, the circuit board 4 and the spring 19 are held between the upper member 2U and the lower member 2L, and the spring 19 is deformed elastically and press-contacted with the spring housing 18 and the ground pattern 17 at multipoints.
