Document Type and Number:
Japanese Patent JP5827247
Kind Code:
B2
Abstract:
[Object] To provide a heater in which occurrence of dielectric breakdown between leads caused by cracks generated at junctions between a resistor and the leads is suppressed and a glow plug having the heater. [Solution] A heater 1 of this invention has a resistor 3 having a folded shape, a pair of leads 4 joined to each end of the resistor 3, an insulating base 2 in which the resistor 3 is buried in the front side thereof and the pair of leads 4 are buried in the rear side thereof, in which the resistor 3 and the leads 4 are overlapped in a direction perpendicular to the axial direction of the leads 4 at junctions 51 and 52 between the resistor 3 and the leads 4 and the rear end of the junction 51 between one end of the resistor 3 and one of the leads 4 is located rearward relative to the rear end of the junction 52 between the other end of the resistor 3 and the other lead 4.
