Abstract

A method for manufacturing a carbon fiber sheet, the method including a carbon fiber forming step of heating a resin sheet to a carbonization temperature at a heating rate of 15,000° C./sec or higher, thereby forming a carbon fiber from the resin sheet. In the carbon fiber forming step, the resin sheet is preferably irradiated with an energy ray having an output density of 130 W/mmor higher and an amount of irradiation energy of 0.05 J/mmor more.
