PROBLEM TO BE SOLVED: To provide a curtain function-adding sheet that is less likely to hinder the deformation of a curtain fold. The above-mentioned problem has a sheet material 1 extending in a longitudinal direction LD and a lateral direction WD, and an adhesive layer 2 provided on a surface of the sheet material 1 which is on a curtain 20 side. A first region 11 that contains a chemical agent that adds a function to the curtain 20 and that is linearly continuous over the entire lengthwise direction LD of the sheet material 1 and that does not have the pressure-sensitive adhesive layer 2, and a pressure-sensitive adhesive layer 2. This is solved by the curtain function-adding sheet 10 in which the second regions 12 are alternately and repeatedly provided in the lateral direction WD.
