<p>[Problem] To provide a heater that inhibits short circuiting due to a wire break, abnormal heat generation or the extension of a crack, and to provide a glow plug provided therewith. [Solution] This heater is characterized: by comprising an insulating substrate, a resistor (3) buried in the insulating substrate, and a lead (4) connected to the resistor (3) and buried in the insulating substrate; in that the resistor (3) and lead (4) are connected so as to overlap in the direction perpendicular to the axial direction of the lead (4); and in that the resistor (3) has a part (31) in the area where the resistor (3) and the lead (4) are connected which is thicker than the other parts in areas other than the connection area.</p> |
