Decorative sheet, method of producing the same, and floor material

PROBLEM TO BE SOLVED: To provide a decorative sheet which ensures sufficient decorative appearance of joint-like grooves, that is comparable to the decorative appearance of a conventional wooden flooring material, and is stably produceable, and to provide a method of producing the dressing sheet, and a floor material using the dressing sheet. SOLUTION: The dressing sheet 1 is produced by forming patterned grooves inclusive of at least the joint-like grooves 126 in a longitudinal direction and a direction B orthogonal to the same, in a surface of a long sheet substrate 11, and filling a coloring agent 13 in the patterned grooves. Herein a depth of the joint-like grooves 12b in the longitudinal direction and the direction B orthogonal to the same is set to 50 to 80 μm, and an opening width of the same is set to 0.7 to 1.2 mm. Thus when the coloring agent 13 is filled in the patterned grooves in the longitudinal direction A according to a wiping method, the coloring agent 13 can be also sufficiently filled in the joint-like grooves 12b in the direction B orthogonal to the longitudinal direction. Further the joint-like grooves in the direction B have sufficient width, and therefore the entire patterned grooves stably exhibit sufficient decorative appearance as the joint-like grooves.
