An impact-resisting anti-lacerative window glass unit or laminate of a sandwich structure is disclosed, which comprises two exterior plate-like member made of a transparent organic polymer (A) and a transparent organic polymer (B) or a transparent inorganic material, respectively, and multilayer structure intermediate films made of at least two kinds of polymers (C). The multilayer structure intermediate films are interposed between two exterior plate-like members. A method of fitting such an impact-resistsing anti-lacerative laminate to a window frame or an automobile is also disclosed, which comprises removing a fitting portion of a hard coated transparent organic polymer (A) and the multilayer structure intermediate films through peeling while remaining at least one layer of a high breaking strength material layer as one of at least two kinds of the polymers (C) in the multilayer structure intermediate films on a person's side, and fitting the laminate to the window frame or an automobile body with an adhesive sealant by utilizing a thus exposed surface.
