[PROBLEM] To provide a heater, which has high reliability and durability, and which suppresses generation of significant stress concentration on an end portion of a bonding section between a resistor and a lead, even if a large current is flown in the resistor in the cases of rapid temperature increase and the like, and to provide a glow plug provided with the heater. [SOLUTION] A heater (1) is provided with: a resistor (3) having a heat-generating unit (4); a lead (8) bonded to an end portion of the resistor (3); and an insulating base body (9) that covers the resistor (3) and the lead (8). The bonding section between the resistor (3) and the lead (8) has, in cross-sectional view, a region where the resistor (3) is spaced apart from the insulator (9) over the whole circumference with the lead (8) therebetween. |
