PROBLEM TO BE SOLVED: To provide a method for continuously producing a biodegradable resin sheet having good flexibility, heat resistance and temperature sensitivity. A method of molding a sheet or the like from a resin composition containing a polylactic acid resin, a plasticizer, a crystal nucleating agent, and a lubricant, wherein the calendar roll is controlled at a specific temperature by a calendar molding method. Step (1) to obtain a sheet or the like by rolling according to step (1), the step (2) for cooling the sheet or the like obtained in step (1) by contacting with a metal roll having a specific surface temperature, and the cooled sheet or the like. , A method including the step (3) of heat-treating by contacting with a metal roll having a specific surface temperature, or two or more of the sheets obtained in the above step (1) and the step (1) at a specific surface temperature. And a biodegradable resin molded article obtained by the production method for obtaining a sheet or the like by crystallization to a relative crystallinity of 30% or more by a method including a step of heat-treating by contact with a metal roll.
