    Abstract: Provided is a heating wire arrangement for a ceramic heater, which is an arrangement of a heating wire on a ceramic substrate in a ceramic heater and emits heat. The heating wire arrangement for the ceramic heater includes a heating wire that is a metal wire member extending in a longitudinal direction and is two-dimensionally arranged on a virtual two-dimensional (2D) plane that is substantially parallel to a top surface of the ceramic substrate.Thus, a uniform heat density may be maintained and a rapid temperature ramp-up may be enabled, unlike a conventional heating wire of a three-dimensional (3D) type.
