The invention provides a method and apparatus for decorative molding capable of reducing a preparation time at the time of replacing a mold and expecting improvement in positioning accuracy of a decorative pattern in a molded article. The method includes supplying a film (7) on which a decorative pattern is formed between a first mold (21) and a second mold (22) in a mold open state of a mold, imaging a mold-side alignment mark (16) recorded in the mold and a film-side alignment mark (15) recorded in the film (7) by a camera, positioning the film (7) with respect to the mold by moving the filmso that the film-side alignment mark (15) comes close to the mold-side alignment mark (16), injecting resin into the mold in a mold closed state in which the film (7) is sandwiched between the firstmold (21) and the second mold (22) and cooling the resin to form a molded article and opening the mold and taking out the molded article in which the decorative pattern of the film (7) is transferredto the surface.
