    • A thermal head is structured to have a substrate, a thermal storage layer formed on one surface of the substrate and made of glass, and heating resistors provided on the thermal storage layer. A plurality of hollow portions are formed at a position spaced apart from a surface where the heating resistors are formed by laser processing using a femtosecond laser, in an area of the thermal storage layer which is opposed to the heating resistors. In this way, to provide a heating resistance element for improving heating efficiency of heating resistors to reduce power consumption, improving strength of a substrate under the heating resistors, and for enabling simple manufacture at a low cost, a thermal head and a printer using the same, and a method of manufacturing a heating resistance element.
    • 热敏头被构造成具有基板,形成在基板的一个表面上并由玻璃制成的热存储层和设置在热存储层上的加热电阻器。 在与加热电阻器相对的区域中,在与通过使用飞秒激光的激光加工形成加热电阻器的表面间隔开的位置处形成多个中空部分。 以这种方式,为了提供一种用于提高加热电阻器的加热效率以降低功耗,提高加热电阻器下的基板的强度并且能够以低成本简单制造的加热电阻元件,热敏头和使用 相同,以及制造耐热元件的方法。
