Abstract
A thermal printing head according to the present invention comprises a heat sink plate carrying, on its one surface, heating elements and a presser cover. The presser cover receives heat from the heat sink plate with a time lag through screws used to mount the presser cover. The heat sink plate is further provided, on its opposite surface, with a compensating plate which serves to prevent or restrain the thermal head from bending due to the delay in heat transmission between the heat sink plate and the presser cover.
