ABSTRACT:
A method of making a flexible sheet heater includes the steps of (i) bonding an electrically conductive fabric and an support member formed of a PET film and a layer of acrylic together, ii) stamp-cutting the electrically conductive fabric to form a heating element having a predetermined loop, iii) attaching two electrical terminals to two distal ends of the heating element respectively, iv) bonding a first flexible protective sheet member to one side of the heating element opposite to the PET film, v) removing the PET film from the heating element; and vi) bonding a second flexible protective sheet member to the other side of the heating element opposite to the first flexible protective sheet member so that the heating element is sandwiched between the first and second flexible protective sheet members.
