摘要： An object of the present invention is to provide a polylactic acid-based decorative body that is polylactic acid resin-based and has a synthetic resin coating film at the uppermost layer so that: the disadvantage of polylactic acid resin can be compensated for; environmental loading can be reduced; a good appearance can be provided; its surface can be prevented from being affected or deteriorated by sweat, hand cream, or the like on the hand of the user; and it can be used in electronic equipment cases. The polylactic acid-based decorative body according to the present invention includes a polylactic acid resin-containing substrate, a polylactic acid resin-containing adhesion layer provided on the substrate, and at least one functional layer that is formed on the adhesion layer by applying an acrylic urethane coating composition, wherein in the acrylic urethane coating composition, the molar ratio of OH groups in an acrylic resin to NCO groups in a polyfunctional isocyanate is 1:4 to 1:6.
