WE CLAIM:
1. A sheet-like material comprising:
a nonwoven fabric including a microfiber having an average single fiber diameter of 0.3 to 7 um; and
an elastomer resin,
wherein
a polymer constituting the microfiber is a polyester obtained from a dicarboxylic acid and/or an ester-forming derivative thereof and a diol,
a 1,2-propanediol-derived component is contained at 1 to 500 ppm in the polyester, and
the elastomer resin is a polyurethane resin (D) including a copolymerized polycarbonate diol (Al) that includes a structural unit derived from an alkanediol (al) having 3 to 5 carbon atoms and a structural unit derived from an alkanediol (a2) having 8 to 20 carbon atoms and that has a molar ratio of the alkanediol (a2) to a total number of moles of the alkanediol (al) and the alkanediol (a2) of 50 to 95 mol%, an organic diisocyanate (B), and a chain extender (C) as essential constituent monomers.
2. The sheet-like material according to claim 1, wherein
the sheet-like material has piloerection on a surface
thereof and the elastomer resin is present in an interior
space of the nonwoven fabric.

3. The sheet-like material according to claim 1 or 2, wherein the polyurethane resin (D) further includes a polycarbonate diol (A2) including a structural unit derived from an alkanediol (a3) having 4 to 6 carbon atoms as an essential constituent monomer.
4 . The sheet-like material according to any one of claims 1 to 3, wherein the elastomer resin has a porous structure and a proportion of micropores having a pore diameter of 0.1 to 20 um occupying all pores of the porous structure is 60% or more.
5. A sheet-like material comprising:
a sheet substrate formed by laminating and integrating a nonwoven fabric having a microfiber as a main body with a woven or knitted fabric; and
an elastomer resin,
wherein
the woven or knitted fabric is composed of fibers including a polyester as a main component, and
a 1,2-propanediol-derived component is contained at 1 to 500 ppm in the polyester.
6. The sheet-like material according to claim 5, wherein

a single fiber diameter of a yarn forming the woven or knitted fabric is 0.3 to 50 um.
