Abstract

PURPOSE:To remedy the thermal strain of ceramic substrate and at the same time, to improve the adhesive property to the cooling base, by establishing a thermal expansion regulation layer on the back surface of ceramic substrate. CONSTITUTION:The substrate 1 is connected to the cooling base 8 with the adhesives layer 9 via the thermal expansion regulation layer 10. Materials forming the thermal expansion regulation layer 9 include metals, alloys, ceramics, thermet, etc. The thermal expansion rate on the surface side on which a thermal head function part is provided and that on the back surface side having the thermal expansion regulation layer 9 are coordinated thereby. The ceramic substrate 1 has the flatness having no thermal strain even at room temperature and the back surface has a suitable surface roughness profitable for adhesion. Therefore, a high-reliable, well-durable thermal head can be provided without using especially complicated jigs.
