Heat-dissipating member and thermal head attached to heat-dissipating member

摘要

A heat-dissipating member includes a heat-dissipating section which is plate-shaped and which is attachable to a heat source directly or indirectly and also includes a plurality of heat-dissipating projections extending from the heat-dissipating section. The heat-dissipating projections are formed by louvering the heat-dissipating section so as to have predetermined heights. The heat-dissipating projections are arranged in increasing order of height in the direction from one end of the heat-dissipating section to an end of the heat-dissipating section that is opposed to the one end. A thermal head includes a plurality of heating elements arranged thereon and a head mount attached to the above heat-dissipating member directly or indirectly.
