An object of the present invention is to provide an automotive ceiling material that is environmentally friendly at the time of disposal, is lightweight, and has excellent rigidity, dimensional stability, and moldability. The present invention provides an automotive ceiling material comprising a crosslinked foam made of a biodegradable resin, wherein the maximum bending load of the crosslinked foam is 1.0 N or more. Further, 90 to 10 parts by weight of polylactic acid having a molar ratio of d-form to l-form of d / l = 98/2 to 70/30 or d / l = 2/98 to 30/70 and biodegradation other than polylactic acid The present invention provides an automobile ceiling material which is a crosslinked foam obtained by using the crosslinked foam obtained by using 10 to 90 parts by weight of a water-soluble polyester resin, a pyrolytic foaming agent, and a crosslinker.
