Abstract
A thermal printer includes a heat sink in which a latent-heat-type heat storage sheet in which a plurality of heat storage materials are added to a base material is attached to a thermal conduction plate. The thermal conduction plate provided in contact with the thermal head. Each of the heat storage materials starts to melt if absorbed heat reaches a predetermined temperature, and the heat storage sheet stores heat while being maintained at a fixed temperature, while each of the heat storage materials melts. A radiation portion that is subjected to surface processing for improving the radiation rate of the heat storage sheet is provided on the surface of the heat storage sheet.
