Abstract
A non-halogen series floor material includes a first intermediate resin layer containing filler of 100 to 400 mass parts with respect to resin ingredient of 100 mass parts, the resin ingredient consisting essentially of resin having no chlorine atom in chemical structure, a surface resin layer integrally formed at an upper surface side of the first intermediate resin layer, the surface resin layer containing resin having no chloride atom in chemical structure and having a thickness of 100 to 1,000 μm, a second intermediate resin layer integrally formed at a lower surface side of the first intermediate resin layer, the second intermediate resin layer containing resin having no chloride atom in chemical structure and filler of 0 to 200 mass parts with respect to resin ingredient of 100 mass parts, and a backing layer integrally formed at a lower surface side of the second intermediate resin layer, the backing layer being formed of a fibrous fabric constituted by fibers containing resin having no chloride atom in chemical structure. A content ratio of the filler in the second intermediate resin layer with respect to the resin ingredient thereof is smaller than a content ratio of the f…
