1. A synthetic resin leather which is used as a skin material for a seat or chair, comprising:
a base cloth layer formed of a knit fabric; and
a synthetic resin layer which has flexibility and is joined to one surface of the base cloth layer, wherein
the knit fabric comprises a first yarn comprising a plurality of multifilament yarns and a second yarn comprising a singular multifilament yarn, wherein said first and second yarns are knitted together,
wherein said multifilament yarn consists of a plurality of twisted long continuous fibers having a thickness ranging from 111 to 444 dtex;
wherein the relationship of the first and second yarns satisfy at least one of the below stipulations:
a. a material of the first yarn is the same as a material of the second yarn and the thickness of the twisted long continuous fibers of the first yarn are different from the thickness of the twisted long continuous fibers of the second yarn;
b. a material of the first yarn is different from a material of the second yarn and the thickness of the twisted long continuous fibers of the first yarn are the same as the thickness of the twisted long continuous fibers of the second yarn;
c. a material of the first yarn is the different from a material of the second yarn and the thickness of the twisted long continuous fibers of the first yarn are different from the thickness of the twisted long continuous fibers of the second yarn;
a dimensional stability of the knit fabric is maintained by heat setting; and
a surface side of the knit fabric is adhered to a back surface side of the synthetic resin layer.
