Abstract
In a thermal head comprising a ceramic substrate, a glaze layer partially formed on the ceramic substrate, heat-generating resistors and electrodes connected to both the ends of the heat-generating resistors, if the width of individual electrodes located outside the glaze layer is made narrower than the width of corresponding electrodes on the glaze layer, formation of a short circuit between adjacent individual electrodes because of the presence of voids on the ceramic substrate can be effectively prevented.
