Abstract

An object of the present invention is to provide a process for laminating works together that are capable of giving laminates a high bonding strength ensured therein. The process for laminating works together laminates a work composed of a resin to a work composed of a resin or glass, the process including a surface activation step of treating a laminating surface of at least the work composed of a resin with vacuum ultraviolet ray or with atmospheric pressure plasma, and a bonding step of bonding together the two works stacked on each other such that a laminating surface of one of the works abuts a laminating surface of the other work, wherein in the surface activation step, the treatment of the laminating surfaces with vacuum ultraviolet ray or with atmospheric pressure plasma is terminated when an accumulated treatment quantity of the vacuum ultraviolet ray or the atmospheric pressure plasma applied to the laminating surfaces is within an initial drop range shown in a variation curve of a water contact angle on the laminating surfaces with respect to the accumulated treatment quantity.
