A heating device which includes two first conducting members and at least a second conducting member, wherein the first conducting members are made of silicone rubber conductor and flexibly pressed into an upper thin layer and a lower thin layer between which is arranged the second conducting member. The first and second conducting members are formed into a whole unit by heat and pressure, which are provided holes at predetermined positions for increasing the contact area to disperse electrical current and conducting wires for connection in parallel or series with the power source. Voltages from 0.1V˜500V AC or DC are all applicable. Hence, the first and second conducting members can dissipate heat evenly. The increased temperature ranges from 1˜230° C. with respect to the environmental temperature thereby preventing the formation of high temperature points. Furthermore, the holes can reduced the electrical current required.
