Zusammenfassung:	A heater that is capable of heating an object to a desired temperature in a short period while minimizing the temperature difference the surface of the object is provided. The heater comprising a plate having a first surface and a second surface, the first surface being a mount surface whereon an object is placed and having a resistive heating member; wherein the resistive heating member is formed in a continuous band having arc bands located on one of two concentric circles of different radii, at least one arc band located on the other circle, and linkage arc band that connects the arc band located on the one circle and the arc band located on the other circle; while the distance between the adjacent linkage arc bands is smaller than the distance between the arc band located on the one circle and the arc band located on the other circle.
