Abstract
A ceramic heater-element to be incorporated into a plug to be pressed into a socket provided on a front inner car-body, thereby providing a cigarette-lighter, which comprises an annular shaped heater-portion having a radially extending gap thereby providing two opposing end-portions, and a pair of electrode-portions, each being extended substantially downwardly from each of the two end-portions while being in a parallel relationship with a center axis of the heater-portion, wherein respective cross-sectional dimensions through which the electric current flows are so arranged that the cross-sectional area of the heater-portion is relatively smaller than either of the cross-sectional areas of the electrode-portions.
