PROBLEM TO BE SOLVED: To provide a manufacturing method of a plastic lens capable of preventing generation of a tape wrinkle in a tape molding method. SOLUTION: The manufacturing method of the plastic lens L1 comprises a mold-assembling process of winding an adhesive tape 4 having a 125μm to 200μm thick tape-like base material and an adhesive layer formed on the tape-like base material around a side surface of two molding molds 2 and 3, both being face to face arranged spaced apart at a predetermined interval, to fix the molding molds 2 and 3 and make a cavity 5 surrounded by the two molding molds 2 and 3 and the adhesive tape 4; an injecting process of injecting a lens material M in the cavity 5; and a superposition and curing process for curing the lens material M.
