PROBLEM TO BE SOLVED: To provide an inter-tunnel seal structure capable of preventing an elastic strip member from being removed from a preceding tunnel.SOLUTION: An inter-tunnel seal structure S which is provided between a preceding tunnel 10b and a following tunnel 10a constructed adjacent thereto includes an elastic seal member 30 provided on the surface of the following tunnel 10a along a tunnel longitudinal direction, and an elastic strip member 50 provided on the surface of the preceding tunnel 10b at a position opposite to the elastic seal member 30. The elastic strip member 50 is fixed to the preceding tunnel 10b in the state of being pressed against the preceding tunnel 10b by a pressing plate part 66, and a protruded strip 70 protruded to the side of the elastic strip member 50 is provided on the surface of the preceding tunnel 10b where the elastic strip member 50 is installed, extending in the tunnel longitudinal direction. In the reverse of the elastic strip member 50, a recessed groove 55 is formed in which the protruded stip 70 is stored.
