Disclosed is a biodegradable resin sheet that contains poly (3-hydroxyalkanoate) and that can be formed into a good film and has excellent barrier properties despite the absence of a crystal nucleating agent. A biodegradable resin sheet 10 of the present invention has a first biodegradable resin layer 11 and a second biodegradable resin layer 12, and the first biodegradable resin layer 11 is made of poly (3 -Hydroxyalkanoate) is contained in an amount of 10 to 90% by mass, and the content ratio of poly (3-hydroxyalkanoate) in the second biodegradable resin layer 12 is less than 10% by mass, and the poly (3 -Hydroxyalkanoate) is 10 to 60% by mass, and is molded by simultaneous multilayer molding.
