A surface heating device comprises a heating element fabricated by braiding plural conductors on a flexible supporter. The surface heating device employs a heating element member which is reduced in thickness or diameter, and thus can be inhibited from providing an uncomfortable touch when sat upon or appearing as a relief on a surface cover of a seat. Also, because a pad is reduced in thickness, the surface cover of the seat can be heated up rapidly. The heating element is fabricated by braiding the conductors, and thus, when loaded with a weight when sat upon, the heating element allows a resultant stress exerted thereon to be dispersed through the conductors, hence being stronger against bending. Moreover, the conductors are inhibited from separating from each other and need no insulating coat.
