A sealing member, a scroll compressor, and a method for manufacturing a sealing member for a scroll compressor are provided. The scroll compressor may include a casing in which a rotational shaft may be provided, a discharge cover fixed to an inside of the casing to partition the inside of the casing into a suction space and a discharge space, a first scroll revolved by rotation of the rotational shaft, a second scroll provided on the first scroll to define a plurality of compression chambers together with the first scroll, the second scroll having an intermediate pressure discharge hole that communicates with a compression chamber of the plurality of compression chambers having an intermediate pressure, a back pressure plate provided on the second scroll, the back pressure plate having an intermediate pressure suction hole that communicates with the intermediate pressure discharge hole, a floating plate movably provided at a side of the back pressure plate to define a back pressure chamber together with the back pressure plate, and a sealing member provided between a surface of the back pressure plate and a surface of the floating plate to prevent a refrigerant from leaking from the back pressure chamber. The sealing member may include a sealing body, and at least one protrusion provided at an incline with respect to a central line that extends in a horizontal direction of the sealing body.
