Abstract (en)
[origin: EP3618566A1] A heater according to the disclosure includes a ceramic body (1) having a rod shape or tubular shape, the ceramic body (1) including, in an outer peripheral surface thereof, a slit-shaped recess (11) extending from a front end toward a rear end of the ceramic body (1); and a heat-generating resistor (2) embedded inside the ceramic body (1) The heat-generating resistor (2) includes a first resistor (21) and a second resistor (22) which are disposed in parallel. The heat-generating resistor (2) includes a first region (31) where the first resistor (21) and the second resistor (22) extend, in a meandering manner, in parallel along a circumferential direction of the ceramic body (1) between the front end and rear end of the ceramic body (1), and a second region (32) located near the slit-shaped recess (11), the second region (32) where only the first resistor (21) extends in a meandering manner.
