PROBLEM TO BE SOLVED: To provide a lining method of a shield tunnel for remarkably reducing a construction period. SOLUTION: An inner floor slab 6 is constructed to be divided into an upper side inner floor slab 60 and a lower side inner floor slab 61. A slide form 3 for constructing a lower side secondary lining part 71 integrated with the lower side inner floor slab 61 in the circumferential direction is assembled, and a precast plate 4 is arranged on the upper face of the slide form 3. Concrete 8 is placed to construct the lower side secondary lining part 71. Then, the slide form 3 for constructing an upper side secondary lining part 70 integrated with the upper side inner floor slab 60 in the circumferential direction is used, and concrete 8 is placed on the upper side secondary lining part 70 to construct the upper side secondary lining part 70.
