A heater of the present disclosure includes: a rod-shaped or cylindrical ceramic body (1) that has a slit-shaped recess (11) in the outer peripheral surface thereof extending from the leading end toward the back end; and a heating resistor (2) embedded inside the ceramic body (1). The heating resistor (2) includes a first resistor (21) and a second resistor (22) disposed in parallel. In addition, the heating resistor (2) has, between the leading end and rear end of the ceramic body (1), a first region (31) where the first resistor (21) and second resistor (22) repeatedly fold back and reciprocate in parallel along the circumferential direction, and a second region (32) that is adjacent to the slit-shaped recess (11) and where only the first resistor (21) reciprocates.
