The present invention provides a laminate-type decorative sheet for use in simultaneous decoration and injection molding, including a base film and at least a decorative layer provided on the base film, the decorative sheet having an elongation at break as measured at 25° C. of 3 to 10%, and an elongation at break as measured at 120° C. of 200% or more.The laminate-type decorative sheet exhibits good conformability to the molding surface of a mold during the course of preforming, and is less likely to produce wrinkling, blistering, breakage, etc. when laminated on and united with a resin molding through injection molding. In addition, the decorative sheet enables easy trimming.
