い易い。In thermal heads, glazed ceramic substrates are generally used from the standpoint of thermal characteristics, but a convex planar glaze as shown in cross-section in FIG. 1 is superior. In FIG. 1, 1 is a ceramic substrate, 2 is a flat glaze, O is a convex glaze, and 4 is a heat generating element. The advantages of the above convex plane glaze are as follows:
The lower convex glaze 6 has heat resistance due to its appropriate thickness, and since the glaze volume is small, its heat capacity is small and its heat storage and radiation properties are good. Further, since the wiring portion is coated with the planar glaze 2, the porosity of the substrate 1 is eliminated, making it easy to process fine patterns and form a multilayer wiring insulating layer.
以下、従来の凸型平面グレーズの製法について図面を用
いて説明する。Hereinafter, a conventional method for manufacturing a convex plane glaze will be described with reference to the drawings.

Next, as shown in FIG. 3, a second glass paste 7 is printed with a width W and a length L2 so as to cover the opening 6. do. Next, heat treatment and firing are performed to obtain a convex plane glaze as shown in FIG. However, as shown in the figure, there is a raised portion 10 at the end of the convex glaze.
is formed. There is warpage on the thermal head board.
The presence of irregularities such as undulations and protrusions is undesirable because it impairs the contact between the heating element and the recording paper.

面グレーズ基板の製造方法を提供する。In some cases, the edge of the substrate including the raised portion 10 at the end of the convex glaze is cut off, but this is wasteful.The present invention has been devised in view of the above drawbacks, and does not cause raised portions at the end. A method for manufacturing a convex planar glaze substrate having a convex glaze as described above is provided.
本発明の一実施例の製造方法について図面を用いて説明

る。In other words, the overlap between the second glass paste and the first glass paste 22 in the width direction corresponds to the contact area between the convex glaze 3 and the flat glaze 2 in the cross-sectional view after heat treatment and firing in FIG. This is a condition for making A smooth.

る。The first glass paste and the second glass paste are
It is necessary to select the properties, and in particular, it is possible to take a combination such that the contact between the first glass paste and the second glass paste increases the surface tension of the second glass paste in the heat-treated softened state. desirable. The first and second glass pastes formed by the combination are brought into contact around the periphery of the convex glaze to be obtained, and the surface tension of the second glass paste is increased when softened, thereby obtaining a preferable convex shape and forming a convex glaze. The stress due to surface tension concentrates on the edges of the glass paste, and the softened glass gathers around the edges, causing the convex glaze to expand in width and increase in height at the edges. The reason is that it is canceled by narrowing the width of .
