０．２６を越えると誘電率。The figure is a triangular diagram showing the composition range of the main components of the composition according to the present invention, and the reason for limiting the composition range of the main components will be explained with reference to the figure. In region A, it becomes difficult to pack the furnace, and the dielectric constant, good dust Q, and insulation resistance decrease. In region B, the temperature coefficient becomes too large on one side, making it impractical. In region C, the temperature coefficient becomes large on the + side and the dielectric constant is also small. D
In this region, sintering becomes difficult, and the dielectric constant, quality Q, and insulation resistance decrease. In addition, in the range of 0〈m≦o, 26, when m is increased, the temperature coefficient shifts to the + side, and by lowering the firing temperature and selecting an appropriate composition, the dielectric constant is large near the temperature coefficient NPO, and the firing temperature can be increased. A low composition is obtained. When m exceeds 0.26, it is a dielectric constant.
良好度Ｑが低下する。Goodness level Q decreases.

The composition can be such that 0.06 to 1.00% by weight of the main component is added in terms of i02. These additives have the effect of improving the sinterability of porcelain, but if the amount added is less than the weight ratio of O and OS, there is no addition effect.1. When the weight coefficient is exceeded, the dielectric constant decreases.
