Claim Text:
1. A heater connectable to an electric power supply portion having a first terminal and a second terminal said heater comprising: an elongate substrate; a first electrical contact provided on said substrate and electrically connectable with the first terminal; a plurality of second electrical contacts provided on said substrate and electrically connectable with the second terminal; a plurality of electrodes including a plurality of first electrodes electrically connected with said first electrical contact and a plurality of second electrodes electrically connected with one of said second electrical contacts, said first electrodes and said second electrodes being arranged alternately with predetermined gaps in a longitudinal direction of said substrate; a plurality of heat generating portions provided between adjacent ones of said electrodes so as to electrically connect between adjacent electrodes, said heat generating portions being capable of generating heat by electric power supply between adjacent electrodes; a first electroconductive line extending in a longitudinal direction and electrically connected to said first electrical contact and said first electrodes; and a second electroconductive line extending in the longitudinal direction and electrically connected to one of said second electrical contacts and one said second electrodes, wherein a cross-sectional area of said first electroconductive line is larger than a cross-sectional area of said second electroconductive line.
