PROBLEM TO BE SOLVED: To provide a roller blind which can surely prevent horizontal displacement of a slat. SOLUTION: In this roller blind, a ladder tape 4 is supported in the state of being suspended from a winding pipe 3 which is rotatably supported on a mounting surface 12, and the multitier slats 5 are supported on the ladder tape 4. The slats 5 can be hoisted or lowered by winding or unwinding the ladder tape 4 around or from the winding pipe 3 together with the slats 5. An anti-horizontal-displacement tape 10 is inserted into the slat 5, and bottom rails 8a and 8b are connected to a lower end of the ladder tape 4. The anti-horizontal-displacement tape 10 is inserted through each of the slats 5 in such a manner as to be relatively displaceable in a vertical direction; an upper end of the anti-horizontal-displacement tape 10 is connected to the winding pipe 3; and a lower end of the anti-horizontal-displacement tape 10 serves as a free end 11 which is not connected to the bottom rails 8a and 8b.
