PROBLEM TO BE SOLVED: To provide a deck material for saving a material, and causing no delay in an extrusion molding speed while avoiding inconvenience of punching an upper plate part by a nail or a machine screw. SOLUTION: This deck material 1 is extrusively molded so as to provide a space 1a partitioned by the upper plate part 11a, a lower plate part 11b and a wall part 12 arranged at a proper interval between both plate parts 11, and is locked on a locking object member 2 in a state of allowing the machine screw 3 to penetrate through the plate parts 11 and the space 1a. The deck material 1 secures a thickness dimension of a part related to locking of the upper plate part 11a larger than a thickness dimension of a part unrelated to the locking by setting the cross-sectional area orthogonal to the extruding direction of the space 1a penetrated by the machine screw 3 in the substantially same as the cross-sectional area orthogonal to the extruding direction of the space 1a unpenetrated by the machine screw 3.
