Abstract
A method of manufacturing a thermal head, including: forming a concave being, which is open on one surface of a support-substrate made of an alumina material; forming an intermediate-layer made of a glass paste by printing the glass paste made of a first-glass-material on the one surface of the support-substrate and baking the glass paste; bonding an upper-substrate to the one surface of the support-substrate by arranging the upper-substrate on the intermediate-layer formed on the one surface of the support-substrate in a laminated state and heating the upper-substrate at a temperature of an annealing point thereof or higher and a softening point thereof or lower, the upper-substrate being made of a second-glass-material having a softening point lower than a softening point of the first-glass-material; and forming a heat generating resistor on a surface of the upper-substrate bonded to the support-substrate at a position opposed to the concave portion.
