Abstract: A heater includes a ceramic body of bar shape; and a heat-generating resistor disposed in an inside of the ceramic body, when viewed in a transverse section, the heat-generating resistor including at least one step portion provided in an outer periphery part of the heat-generating resistor, the at least one step portion having such a shape that semicircular portions bisected in a diametrical direction of the heat-generating resistor deviate from each other along the diametrical direction.

Abstract: A heater includes: a ceramic body having a rod-like shape; and a heat generating resistor embedded in the ceramic body, the heat generating resistor including a first straight line section, a second straight line section which is disposed alongside the first straight line section, and a folded section which connects the first straight line section and the second straight line section, in a transverse cross section of the heater, the first straight line section having a shape having a first major axis, the second straight line section having a shape having a second major axis, the second major axis being inclined with respect to the first major axis, a centroid of the first straight line section and the second straight line section being deviated from a centroid of the ceramic body to a side on which a distance between the first major axis and the second major axis is narrower.
