Abstract

Provided is a laminated body, said laminated body being a laminated cloth the back surface of which has excellent properties against tangling and abrasion and good separability from the skin and which has a good texture and a favorable appearance and is comfortable to wear when made into clothing. The laminated cloth includes a front surface layer, a middle layer and a back surface layer, said layers being stacked one on another, wherein: the front surface layer comprises one member selected from the group consisting of a woven fabric, a knitted fabric and a non-woven fabric; the middle layer comprises a resin film or a non-woven fabric; and the back surface layer comprises a circular knitted fabric in which filament yarn of 60 dtex or less is used at least in part thereof and which is configured from knitting stitches and tack stitches, 9 to 72 said tack stitches being disposed per area of 12 wales×12 courses.
