<p>The present invention provides a highly reliable heater which minimizes change in resistance value even when used at high temperatures, and a glow plug equipped with the heater. This heater comprises: a heating element (2) containing V, Nb, Ta, Mo, or W as a principal component; a lead (3) joined to each end of the heating element (2); and an insulating base body (1) in which the heating element (2) and the lead (3) are embedded. The heating element (2) and the insulating base body (1) are sintered into a single body and made from a sintered compact. The heating element (2) includes a compound (6) containing at least one element different from the element that is a principal component of said heating element (2) among V, Nb, Ta, Cr, Mo, W, Mn, or Fe. Said element is not substantially contained in the periphery of the heating element (2) inside the insulating base body (1).</p> |
