A subfloor material， a subfloor structure， the floor finishing structure， a subfloor construction method， and the floor finishing construction method

SUBJECT of the Invention The subfloor material， the subfloor structure， the floor finishing structure， subfloor construction method， and the floor finishing construction method which can utilize various floor covering material are provided without impairing the sound-insulating property with respect to a lightweight impact noise， while it is excellent in a workability. PROBLEM to be solved The plywood 2 and the nonwoven fabric 3 joined to surface 2a of one side of this plywood 2 are included， While being stuck to the subfloor material 1 via the adhesive agent， the subfloor structure 10 where the subfloor material 1 and the subfloor material 1 are stuck to the concrete floor 5 via the double-sided tape 4， and the floor covering material 6， The subfloor construction method which sticks the floor finishing structure 11 couple|bonded by the nail 7 and the subfloor material 1 to the concrete floor 5 with the double-sided tape 4， and the floor covering material 6 are laminated|stacked on the subfloor material 1 via an adhesive agent， The floor finishing construction method couple|bonded with the nail 7.
