PROBLEM TO BE SOLVED: To provide a floor material which prevents a resident from feeling cold when touching the material even in winter and manufactured by tongue and groove joints by taking construction performance and ease of use into account. SOLUTION: This floor material A includes a floor finish material 1 constituted by laminating a decorative layer 2, a surface reinforcing layer 3, a hard foaming body layer 4, and a rear surface reinforcing layer 5 sequentially and integrally, forming a female solid part 10 and a male solid part 14 on an end face 1a of a butt end, and applying tongue and groove joints and a heat insulating layer 20 laminated and integrated on/with the rear surface of the floor finish material 1. The decorative layer 2 is formed of a resin-made decorative sheet having minute recessed and projecting parts 2a on its surface or a coated material. The surface and rear surface reinforcing layers 3, 5 are formed of an inorganic fiber sheet filled with a moisture hardening type resin or a reaction type resin, and tongue and groove joints are applied on the end face 1a of the butt end of the floor finish material 1.
