Abstract

PURPOSE:To reduce the weight of a thermal head and to improve the heat radiating effect of the head by interposing a thermally conductive heat radiating plate between a heat resistant insulating substrate and a heat radiating base and interposing a thermoelectric insulating plate between a multilayer circuit board and the base. CONSTITUTION:A heat resistant insulating substrate 2 made of glazed alumina or the like is provided through a heat radiating plate 22 having good thermal conduction such as iron series material or the like on part of a heat radiating base 21 made of aluminum or the like, and a common electrode 4, a heating resistor 3 and an isolating electrode 5 are provided on the substrate. A multilayer circuit board 11 is provided through a thermoelectric insulating plate 23 on the other art of the base 21. A semiconductor device is provided on the board 11 or between the substrate 2 and the board 11. A coating film 8 is preferably formed on the lower surface of the device 7. A conductive pattern 24 is formed on the back surface of the board 11, and the pattern 24 is preferably electrically connected to a signal line 12 through a through hole 25.
