Abstract
A thermal printing head has a plurality of heating resistors formed on an insulating substrate with spaces of a predetermined width being provided between adjacent resistors. In another embodiment, these spaces are filled with intermediate layers of a material such as glass. With this structure, temperature distribution produced by the heating resistors becomes substantially flat, whereby the power consumption of the thermal printing head can be reduced, and the thermal efficiency can be improved.
