THERMAL RECORDING HEAD

摘要: PURPOSE:To obtain the titled head having high durability while good printing quality, by a method wherein, in thermal recording curve-shaped heating element consisting of main portion and curved portion, widths are set to be special dimensions. CONSTITUTION:A layer 108 is attached on glaze 116 being fixed an insulator substrate 103, thereon opposed electrodes common electrode 109 individual signal 110 disposed respectively opposedly each other across space 111, attached. In this manner, 102 formed 111. The under 111 between 109, coated protected protecting 117 made Ta2O5. Measurement temperature distribution within which temperatures continuously dotted as width W1 108a W2 thereof changed, shows that sufficient service life obtained with range 15-35mum, additionally from excessive burden more than 15mum. When setting mentioned above, durable for long period use obtained, thus, extending head.
