Abstract

The present invention relates to a heating resistor element and manufacture method thereof, and a thermal head and a printer. Provided is a heating resistor element (1), including: an insulating substrate (9); a heat accumulating layer (10) bonded to a surface of the insulating substrate (9); and a heating resistor (11) provided on the heat accumulating layer (10), in which: on at least one of bonded surfaces (9a) between the insulating substrate (9) and the heat accumulating layer (10), at least one of the insulating substrate (9) and the heat accumulating layer (10) is provided with a concave portion (16) in a region opposed to the heating resistor (11) to form a hollow portion (17); an inner surface arranged in the hollow portion of the heat accumulating layer is formed glossily, and the inner surface being processed to have surface roughness (Ra) of 0.2 mum or more. Accordingly, heat accumulation in a gas of the hollow portion (17) can be suppressed to improve printing quality.

Description

technical field [0001] The invention relates to a heating resistance element, a manufacturing method thereof, a thermal head and a printer. Background technique [0002] Generally, in a heating resistor provided in a thermal head of a printer, in order to improve the heating efficiency of the heating resistor and reduce power consumption, a hollow portion is formed in a region opposite to the heating resistor, and the hollow portion is used as a A thermal insulation layer of low thermal conductivity, thereby controlling the heat flow from the heating resistor to the side of the isolated substrate (see eg JP 2007-83532A). [0003] As a method of forming the hollow portion, a method is employed in which a silicon substrate is subjected to etching or laser processing, and a recessed portion (having a depth of 1 μm or more and 100 μm or less) is formed to Anodic bonding is performed to bond thereto a thin plate glass (having a thickness of 10 μm to 100 μm) serving as a heat gat...
