More Information
Summary:A thin film type heater including a substrate 10, a plurality of single thickness unit heating layers 20 coated on the substrate 10 in a predetermined pattern, an electrode layer 30 for interconnecting the unit heating layers to form a current path and a protective layer 40 for protecting the heating layer 20 and the electrode layer 30. The method of manufacture involves using a metal mask to define the area of cover for each of the three individual layers. Connection terminals 31 are provided for connection of the heater to an electrical supply. The heater can be used in apparatus such as a boiler-type humidifier of a water heater.
