PROBLEM TO BE SOLVED: To provide a method for producing a composite member in which the specular surface of the functional element of an optical element in which a holding member is combined with the functional element is molded by transfer processing and to create a method for holding the holding member in a mold so that the deformation of the holding member by the mold during the transfer processing is eliminated and the deterioration of the straightness of the functional element held by the holding member by the deformation of the holding member is prevented. SOLUTION: On the premise of the method for producing a composite optical element in which part of the plastic functional element 3 is engaged with the holding member 2 to combine them, and the specular surface of the plastic functional element is transferred, when the functional element 3 is held by a cavity insert 1 for transfer processing, the holding member is lifted from the transfer mold D to prevent the holding member 2 from being held by the transfer mold, and the transfer is done in this state. |
