An electric heater plate is disclosed which is formed on one surface of a sheet of tempered glass. The one surface of the tempered glass sheet has a plurality of thin lines of a silver ceramic material bonded thereto, the thin lines extending in a generally parallel but spaced apart relationship across the sheet of glass. Left hand and right hand end portions of the plurality of thin lines are interconnected by a thin interconnection strip of a silver ceramic material. A small terminal area of silver ceramic material is also associated with each of the interconnection strips located at opposite ends of the plurality of thin lines. A termination area is also bonded to the one surface of the sheet of tempered glass at a position spaced from the left hand and right hand interconnection strips. A thin copper strip is bonded to each of the terminal areas and the termination area associated with the left hand or the right hand interconnection strip to electrically interconnect the same. Electrical leads are connected to each of the pair of termination areas to provide a connection to a power system. When the power system is actuated, current flows through the plurality of thin lines in order to heat the tempered glass sheet. If the tempered glass sheet is installed as the rear window of a motor vehicle, the heat generated by flowing the current through the thin lines can de-fog and de-ice the window.
