Provided is a base body for an artificial leather comprising a polyester excellent in thermostability during melt molding. That is, provided is a conjugated fiber comprising a polyester which exhibits only a small reduction in intrinsic viscosity during melt molding. The base body for an artificial leather comprises an intertwined fiber body mainly comprising an ultrafine fiber having a 0.01 to 10 µm fiber diameter and an elastic polymer, the ultrafine fiber comprising, as a constituent polymer, a polyester obtained from a dicarboxylic acid and/or an ester-forming derivative thereof, and a diol, the polyester containing 15 to 500 ppm of a 1,2-propanediol-derived component. |
