An object of the present invention is to provide a retardation film imparted with high retardation stability and a method for producing the same. A film made of a thermoplastic resin and oriented in at least a uniaxial direction, wherein the glass transition temperature of the thermoplastic resin is in a range of 100 to 180 ° C., and an endothermic amount at the glass transition temperature is 0. A retardation film in the range of 0.01 to 5.0 J / g. [Selection figure] None |
