PROBLEM TO BE SOLVED: To provide a wrinkle detection device for a transport membrane capable of surely preventing generation of wrinkle and its method. SOLUTION: The wrinkle detection device 3 for the transport membrane 2 detects the generation of wrinkle generated on the transport membrane 2 transported along a transport line 1, and includes a light source part 32 for irradiating an irradiation light toward the surface of the transport membrane 2, a camera part 33 which receives the irradiation light irradiated from the light source part 32 and images a two-dimensional shape of the transport membrane 2, a detection part 34 which detects a predetermined data value of patterns 20 composed of a plurality of linear ridge lines 21, 21 and etc. emerged on the surface of the transport membrane 2 from the imaging data picked up with the camera part 33, and a determination part 35 which determines whether or not the predetermined data value detected by the detection part is within the range of the data value when the wrinkle is generated on the transport membrane 2.
