A weatherstrip manufacturing method is a method for manufacturing a weatherstrip which includes a trim portion where an insert is embedded. The insert includes short connecting portions that connect strips at substantially regular intervals, and a long connecting portion having a larger length than each length of the short connecting portions. The method includes an extrusion molding step for covering the insert with a polymer material, a cut-off portion forming step for cutting off a part of a long interval portion including the long connecting portion in the long interval portion where the long connecting portion is embedded to form a cut-off portion, and a cutting step for cutting the cut-off portion in a crossing direction orthogonal to a longitudinal direction to divide the weatherstrip in the longitudinal direction.
