PROBLEM TO BE SOLVED: To provide a segment-connecting structure, absorbing an assembling construction error between both tunnels, while reducing the construction period. SOLUTION: A female structural member 20 having a box extract part 21 is formed on one segment, and a male structural member 30, loosely fitted to the box extract part 21 with a gap for absorbing construction errors, is formed on the other segment 3. In the female structural member 20, a second end plate 25 is formed at the box extract part 21 side wall surface opposite to a first end plate 35 in loosely fitting to the male structural member 30; and a U-shaped groove part 27 locking with a projecting part, in the male structure member 20, is provided on the side opposite to the box extract part 21 sidewall surface. In the male structural member 30 and the female structural member 20, stress transmitting beams 26, 36 are respectively provided, extending over at least two tunnels in the axial direction of the tunnel.
