PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminate which includes applying a coating layer formed of two or more layers onto a support base material by a die coat method, irradiating the coating layer with active energy rays, drying and curing the coating layer, and thereby forming a coating layer formed from two or more layers having interlayer adhesion and mutually different functions with one application.SOLUTION: A method for manufacturing a laminate which laminates a coating layer formed from two or more layers on at least one surface of a support base material with a die coat method includes: a step (step 1) of applying two or more coating compositions onto the support base material with the die coat method to form a coating film; a step (step 2) of irradiating the coating film with active energy rays; a step (step 3) of drying the coating film; and a step (step 4) of curing the coating film, in this order, once.SELECTED DRAWING: None 【課題】２層以上からなる塗布層をダイコート法により支持基材上に塗布し、活性エネルギー線を照射し、乾燥、硬化することで、層間密着性を有し、それぞれ異なる機能を持つ２層以上からなる塗布層を、一回の塗布で形成する積層体の製造方法を提供することである【解決手段】２層以上からなる塗布層をダイコート法により支持基材の少なくとも片面に積層する積層体の製造方法であって、２種類以上の塗料組成物をダイコート法により支持基材上に塗布し塗膜を形成する工程（工程１）、前記塗膜に活性エネルギー線を照射する工程（工程２）、前記塗膜を乾燥する工程（工程３）、前記塗膜を硬化する工程（工程４）をこの順に１回で行うことを特徴とする、積層体の製造方法。【選択図】なし
