The purpose of the present invention is to provide: a laminate which can be used as a microfluidic chip in which the bonding strength is maintained, while exhibiting a good appearance, and in which the risk of liquid leakage from a channel is suppressed; and a method for producing the laminate. The laminate according to the present invention is obtained by bonding a substrate with channels, which is made of a cyclic olefin polymer, and a cover material, which is made of a cyclic olefin polymer, with a binder, which is made of a mixture of two or more cyclic olefin polymers, being interposed therebetween. The glass transition temperature of the mixture of cyclic olefin polymers as the material of the binder is at least 20 DEG C lower than both the glass transition temperature of the cyclic olefin polymer as the material of the channel-equipped substrate and the glass transition temperature of the cyclic olefin polymer as the material of the lid material, and is 68-138 DEG C. 本发明的目的在于提供一种层叠体及其制造方法，上述层叠体能够用作在维持接
