Abstract
Provided is a resin sheet for thermoforming, the resin sheet containing a poly(3-hydroxybutyrate) resin. A difference between a melting point peak temperature and a melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin is 10° C. or more. The sheet has a thickness of 0.15 to 1 mm. The melt viscosity of the poly(3-hydroxybutyrate) resin at 160° C. is preferably 10000 poise or more.
