<p>Provided is a spiral tube-like heater configured so that temperature can be accurately controlled over a wide range and that safety problems due to the breaking of a heat generation body are reduced. A spiral tube-like heater (1) in which a first heat-resistant resin tape (4) and a second heat-resistant resin tape (6) are stacked on each other while two or more longitudinally extending heat generation bodies (2) are sandwiched therebetween and while an adhesive layer (10) is provided therebetween. The spiral tube-like heater (1) is characterized in that the two or more heat generation bodies (2) are arranged so as to be insulated from each other and are respectively and independently connected to different lead wires (8) coming from the outside.</p>
