A method of manufacturing an activated carbon fiber soft electric heating product for overcoming existing problems including uneven temperature rise and heat dissipation at surfaces of the product, unbendable feature, short life and poor safety. An activated carbon fiber cloth and a woven fiber cloth of the activated carbon fiber soft electric heating product are fixed by an epoxy resin layer, and a conducting copper net is disposed between the activated carbon fiber cloth and the epoxy resin layer and coupled to a power input wire. The manufacturing method includes the steps of: (1) spraying an epoxy resin on a surface of the woven fiber cloth, and bake-drying and hot pressing the woven fiber cloth; and (2) connecting the conducting copper net and the power input wire, laying the activated carbon fiber cloth, and performing a second-time hot pressing. Meanwhile, carbon fiber constitutes a heat generating surface with the advantages of a light weight, a soft texture, a bendable feature, a uniform electric heating performance, a fast temperature rise, a highly safe, reliable and long life feature. In addition, the method of the invention involves a simple technical skill and an easy operation.
