Thermal head

Abstract

Abstract PURPOSE:To obtain a thermal head for two-dimensional pattern recording which enables high speed printing of high reliability by mounting the functional circuit for driving on the back side of the substrate and integrating the thermal head installed on the face side. CONSTITUTION:The two-dimensianal pattern composed of the heat-generating resistor 2 connected to the feeding conductor 3 is arranged on the surface of the ceramic substrate 1. Meanwhile, the active element 6 driving said heat-generating resistor is mounted on the back of the substrate 1, the element 6 is connected to the feeding conductor 3 of the heat-generating resistor 2 via the wiring 7, the throughhole 4 and forms the thermal head (mark 8 is in- and output pad, and 5 is a cap).
