PROBLEM TO BE SOLVED: To provide a method of manufacturing a decorative molded body capable of controlling unevenness manifestation or molding time without requiring a physical method such as embossing in a vacuum forming simultaneous decoration method, and having unevenness that can be favorably decorated even when an adherend that is weak against heat is used.SOLUTION: The method of manufacturing a decorative molded body having unevenness in a decorative surface includes: a process (1) of causing a film thickness difference between a portion A and a portion B by irradiating an infrared ray on the portion A of a resin sheet and the portion B adjacent to the portion A in the same plane of the resin sheet in a state of holding the heat shrinkable resin sheet having the portion A provided with ink including metal oxide such that surface temperatures of the portion A and the portion B are different, and such that at least the surface temperature of the portion A becomes a surface temperature the same or more than an orientation return strength inflection point temperature T of the resin sheet; and a process (2) of adhering and integrating the resin sheet to the adherend by a vacuum forming method. |
