The present invention provides a base fabric for a disposable textile product that excels in moisture transpiration ability, heat dissipation ability, and moisture permeability. The invention also provides the disposable textile product that uses the base fabric for the disposable textile product, which excels in feeling in wearing and contact with the skin and also excels in moisture transpiration ability, heat dissipation ability, and moisture permeability. The base fabric for the disposable textile product is configured of a laminated sheet 30 which has a first fibrous sheet 2 and a second fibrous sheet 3 having air permeability and a fiber material 4 interposed between the first fibrous sheet 2 and the second fibrous sheet 3 and having liquid diffusibility, and in which the first fibrous sheet 2 and the second fibrous sheet 3 and the fiber material 4 are laminated together with an elastic member 5. The laminated sheet 30 forms a composite layer 31 in which a fiber layer having the air permeability and a fiber layer having the liquid diffusibility are laminated. The laminated sheet 30 has a shirring portion 6 in which an uneven surface is formed by the composite layer 31. Elasticity is imparted to the laminated sheet 30.
