The backing material 3 is made of a non-slip non-woven fabric or the like.

A shape-retaining sheet 5, which will be described in detail later, is laminated on the back surface of the skin material 2 via a resin adhesive 41 such as a hot-melt adhesive. The backing material 3 is laminated via the resin adhesive 42 to form the automobile floor mat 1 of the present embodiment.

In this embodiment, the shape-retaining sheet 5 is made of a woven fabric made up of a plurality of plastic wires 51 .

Specifically, as shown in FIGS. 2 and 3, the plastic wire rod 51 used in this embodiment can be freely bent by an operator's manual operation in the same manner as a wire, and retains its shape after being bent. It is a wire material made of synthetic resin that can be plastically deformed.

In the present embodiment, the plastic wire 51 is preferably made of a twisted yarn obtained by twisting a plurality of plastically deformable thin wires 52 made of synthetic resin, as shown in FIG. 4, in consideration of strength and the like. . When twisted yarn is used, the twisting method such as the number of twists and the twisting direction is not particularly limited, and the twisting method may be appropriately determined according to the usage conditions.

However, in the present invention, the plastic wire 51 is not limited to the twisted yarn, and a single yarn composed of one yarn may be used.

Here, in the present embodiment, as the plastic wire 51 and the fine wire 52 that constitutes the wire, the product name "Technorot" manufactured by Mitsui Chemicals, Inc., the product name "Forte" manufactured by Sekisui Seisei Kogyo Co., Ltd., etc. are used. It can be used preferably.
