  • Thermal head and printing device
    Patent number: 8098268
    Abstract: A thermal head includes a glass layer provided with a groove section formed inside the glass layer, a heat generating resistor disposed outside the glass layer, and a pair of electrodes provided to both sides of the heat generating resistor, wherein a part of the heat generating resistor exposed between the pair of electrodes is defined as a heat generating section, and at least one of the pair of electrodes has a smaller width in an end section on an opposite side to a side of the heat generating section than a width of an end section on the side of the heat generating section.
    Type: Grant
    Filed: March 15, 2007
    Date of Patent: January 17, 2012
    Assignee: Sony Corporation
