Abstract: An electric heater includes a substrate and a plane heating element disposed on one surface of the substrate. The plane heating element includes a first pattern portion including a start point and an end point, a second pattern portion that surrounds at least a portion of the first pattern portion and includes a start point and an end point, which are located at an innermost side of the second pattern portion, and a third pattern portion that surrounds at least a portion of the second pattern portion and includes a start point and the end point, which are located at an outermost side of the third pattern portion. The first pattern portion includes a plurality of first tracks that are space apart from each other and have an arc shape that is increasing in length from a center to an outermost side of the first pattern portion, the second pattern portion includes a plurality of second tracks spaced apart from each other and having an arc shape that is increasing in length from the innermost side to an outermost side of the second pattern portion, the third pattern portion includes a plurality of third tracks spaced apart from each other and having an arc shape that is increasing in length from an innermost side to the outermost side of the third portion, and a width of a third track is wider than a width of a first track.

Abstract: An electric heater includes a substrate; a first plane heating element disposed on a surface of the substrate; and a second plane heating element disposed on the surface of the substrate so as to be located outside the first plane heating element. The first plane heating element includes a first pattern portion having a start point and an end point, and a pair of first electrode portions connected to the first pattern portion. The second plane heating element includes a second pattern portion that surrounds a portion of an outer circumference of the first pattern portion, has a start point and an end point, and has an opening portion at one side thereof; and a pair of second electrode portions connected to the second pattern portion.

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.
