Abstract (en)
A thermal head of a real edge type which includes an insulative substrate (B), a plurality of heat generating resistors (R) provided at one edge on an upper surface of the insulative substrate in a parallel relation to the one edge, and individual lead patterns (Se) and a common lead pattern (Ce) provided at an edge of each of the heat generating resistors (R) to extend in a direction at right angles with an aligning direction of the heat generating resistors, in which the extended length of the respective common lead (Ce) patterns is made longer than those of the individual lead patterns (Se) so as to project beyond bonding pad portions of the individual lead patterns, with a common collective pattern directed in a parallel relation with the aligning direction of the heat generating resistors (R) being provided at the extended projecting end portions of the common lead patterns.
