A method for recycling optical device constituent members, wherein a transparent adhesive material is softened by heating and is crosslinked by light irradiation, an optical device constituent laminate having a constitution in which two optical device constituent members are bonded via a transparent adhesive material in a pre-crosslinked state is used as a recycle starting material, and the method including: heating at least the transparent adhesive material of the optical device constituent laminate; standing the optical device constituent laminate; hanging a linear member along an end edge of the transparent adhesive material located at an upper end edge of the optical device constituent laminate; dividing the transparent adhesive material by applying a load by the linear member; and producing the two optical device constituent members to which a divided one-side transparent adhesive material adheres.
