Abstract

An electric heater includes a substrate (an insulating material capable of forming a conductor pattern on a surface of an insulating substrate), a first plane heating element formed on one surface of the substrate, and a second plane heating element formed on one surface of the substrate to be located outside the first plane heating element. The first plane heating element includes a first pattern portion connecting a start point with an end point located in a first zone, a pair of first electrodes located outside the first zone, and a pair of first connectors connecting the first pattern portion with the first electrodes. The second plane heating element includes a second pattern portion located in a second zone surrounding the first zone and connecting a start point with an end point, and at least some of the first connectors are located in the second zone.
