ABSTRACT:
A thermal head of an end-heating type for use in printers or facsmiles comprises a non-conductive substrate having upper and under plain side surfaces and front end face and mounted at the under plain said surfaces thereof on a support member. The front end face of the substrate extending between the upper and under plain side surfaces is adapted to be held in sliding contact with a recording medium such as thermo-sensitive sheet or ink transfer sheet. A plurality of spaced heat-generating resistors for forming heat-generating dots are provided on the upper plain surface of the substrate and arranged along the front end face of the substrate. Each of the heat-generating resistors has a front end which extends closely adjacent to the front end face of the substrate. Electrodes for feeding electricity to the heat-generating resistors are also provided on the upper plain side surface of the substrate. The heat-generating resistors and electrodes can be easily formed only on the upper plain side surface of the substrate by an ordinary film formation process.
