PROBLEM TO BE SOLVED: To provide a manufacturing method of a seal structure which can shorten construction time of a seal structure.SOLUTION: A manufacturing method of a seal structure includes: an expansion/contraction seal material forming step of forming an expansion/contraction seal material 7 which has water tightness and expands/contracts, by curing a sealing material having fluidity beforehand; a filling step of filling, with a filler seal material 4, a portion between an outer peripheral surface of an arrangement member 2 and an inner peripheral surface of a through-hole 13; and an expansion/contraction seal material fixing step of fixing the expansion/contraction seal material 7 formed in the expansion/contraction seal material forming step on the outdoor side of the filler seal material 4, after the filling step. In the expansion/contraction seal material fixing step, the expansion/contraction seal material 7 in which the arrangement member 2 is inserted in the through-hole 13 is adhered to the outer peripheral surface of the arrangement member 2 and the inner peripheral surface of the through-hole 13, and fixed.SELECTED DRAWING: Figure 1 |
