PROBLEM TO BE SOLVED: To provide a sheet for curing a moisture permeable floor which can make use of the moisture permeability of a sheet base material as it is. SOLUTION: The sheet for curing the moisture permeable floor and manufacturing method therefor have the sheet base material 2 having moisture permeable and waterproofing performance and an adhesive layer 3 which is formed by applying a hot melt adhesive on one of its surfaces in a droplet or fiber state. The water vapor transmission of the sheet for curing the moisture permeable floor is 1,000-20,000 g/m<SP>2</SP>24h, and its watertightness is greater than or equal to 50 cm H<SB>2</SB>O. The adhesive layer 3 is formed by applying the hot melt adhesive in a curtain spray state, and the sheet base material 2 is a composite sheet formed by laminating a micro-porous moisture permeable waterproofing film and a moisture permeable reinforcing material. The micro-porous moisture permeable waterproofing film consists of polyolefin resin and an inorganic filler, and the sheet base material 2 is the composite sheet formed by laminating the moisture permeable reinforcing material on both surfaces of the moisture permeable waterproofing film.
