Abstract

A thermal printhead for use in a thermal recording machine includes a substrate on which a plurality of heat-producing elements are formed in the form of a linear array and a plurality of I.C. driver chips provided along one side of the linear array, and the I.C. driver chip includes output pads formed in a line spaced apart from one another on its surface along one side thereof. Using such an I.C. driver chip, the linear array density of 8 elements/mm and thus recording density of 8 dots/mm is obtained.
