Abstract
A heater includes: a substrate; a first electrical contact; a plurality of second electrical contacts; an electroconductive line portion electrically connected with the first electrical contact; a plurality of electrode portions including first electrode portions electrically connected with the first electrical contact through the electroconductive line portion and second electrode portions electrically connected with the second electrical contacts; and a plurality of heat generating portions provided between adjacent ones of the electrode portions. The cross-section of the electroconductive line portion in a side closer to the first electrical contact than the plurality of heat generating portions with respect to the longitudinal direction is larger than the cross-section of a predetermined electrode portion, between adjacent heat generating portions, of the plurality of electrode portions.
