Abstract
A divisional-type thermal printhead comprises an elongate support member, and a crow of unit head substrates each fixed on the support member and carrying a resistor line extending longitudinally of the support member. A pair of V-shaped boundary spaces is formed between each two adjacent unit head substrates to extend transversely from the resistor line in opposite directions. A resin spacer is formed in each of the boundary spaces to prevent warping or bending of the printhead.
