Abstract
A thermal head having electrode wiring lines in a narrow wiring region, in which a line and a space are narrow, with good pattern accuracy and a method of manufacturing the same are provided. A thermal head includes: a plurality of heating resistors arranged in a line at predetermined pitches there between on a protruding level difference part of a glazed substrate; bent wiring lines each of which serves to electrically connect a pair of adjacent heating resistors to each other; a common wiring line and individual wiring lines used to cause the pair of adjacent heating resistors to be electrically conducted through each of the bent wiring lines; and bonding pads formed on one ends of the individual wiring lines. The common wiring line has a narrow wiring region located between the bonding pads arranged in a line and a wide wiring region wider than the narrow wiring region. The wide wiring region is formed using a conductor layer and a resistor layer made of the same material as the heating resistors, and the narrow wiring region is formed using only the conductor layer without the resistor layer.
