摘要： Provided is a resin sheet including a plurality of aspheric sections having low variation of thickness precision and high shape precision. A method of producing a resin sheet includes hot press forming a thermoplastic resin film formed using a thermoplastic resin so as to produce a resin sheet including a plurality of aspheric sections that are separated from one another. The hot press forming is performed by increasing the pressing pressure to a final pressing pressure with an average pressure increase rate of 0.1 MPa/s or less at a pressing temperature that is at least 40° C. higher than the glass-transition temperature of the thermoplastic resin.
