Abstract
A thermal head is provided with increased contact pressure between a heat generating portion and a printing medium to increase printing quality with a low heat loss. The thermal head includes: a plurality of heat generating resistors formed via an insulating layer; a driver circuit unit for driving the plurality of heat generating resistors to generate a heat; a wiring for connecting the driver circuit unit to the plurality of heat generating resistors; a protecting film formed to cover the plurality of heat generating resistors, the driver circuit unit and the wiring. The plurality of heat generating resistors, the driver circuit unit, the wiring and the protecting film are formed on a substrate. A thermal insulating layer having a thermal conductivity smaller than 0.5 W/m·K and having a maximum thickness of larger than 10 μm is provided between the heat generating resistor and the substrate.
