A printing apparatus includes a support portion configured to support a part of a printing medium to be transported, a heating portion configured to heat the part of the printing medium supported by the support portion, and a curved portion disposed upstream of the support portion in a transport path of the printing medium and including a curved surface that curves the transport path. The curved portion is formed of a member having a lower thermal conductivity than the support portion. In addition, the temperature of the curved portion is lower than the temperature of the support portion.
