Abstract
PURPOSE:To arbitrarily set the temperature characteristics of heating element in a thermal printing head without changing the outside shape and outside dimension of the thermal printing head, by changing the mixing ratio of either a granular substance having a specific heat or a heat conductivity different from that of a base material or bubbles in the base material of a radiating board. CONSTITUTION:In a base material in a radiating board 4 of aluminum alloy a granular substance 5 having a specific heat or a heat conductivity different from that of aluminum is included by an appropriate amount, whereby the aluminum alloy changes in specific heat or heat transfer coefficient. In this manner, by changing the mixing ratio of the granular substance 5 to the base material, the heat capacity or heat transfer coefficient in the radiating board 4 can be arbitrarily changed under the same condition of the radiating board 4 in thickness T, width dimension S, and length dimension L. The heat capacity or heat transfer coefficient in the radiating board 4 can also be changed under the same condition of the radiating board 4 in thickness T, width dimension S, and length dimension L by an alternative method in which; fine bubbles 6 are included into the base material in the radiating board 4 to make the base material a form metal.
