Method of manufacturing heating device by screen printing

A method of manufacturing a heating device, comprising:

• preparing a substrate having a curved surface;
• and
• forming a heating body on the substrate, the heating body configured to generate heat with a supply of electric current, the forming of the heating body including
• pressing a screen toward the substrate with an aid of a pressing member while rotating the substrate and moving the screen, and
• transferring application liquid at a transfer position in which the screen and substrate are in contact to form the heating body to the substrate through the screen
• wherein, in the forming of the heating body, the pressing member is in contact with the screen at a position on an upstream side with respect to the transfer position in a direction of movement of the screen.
