Abstract

PURPOSE:To achieve a higher closeness of a gauge section, by forming and sintering a material powder comprising TiB2 and ZrB2 and a compound matter containing them to make the gauge section. CONSTITUTION:A material powder comprising at least one kind of material selected from TiB2 and ZrB2 and a compound matter containing at least one thereof is formed and sintered to make a gauge element body 20, which is cut with an electric discharge machining device containing an electrode made of material the same as that of the gauge element body 20. A mirror finishing of the gauge element body 20 is performed using an abrasive powder with the max. particle size of below 1.0mum made of material selected from TiB2 and ZrB2 and a compound matter thereof. This can improve the closeness of the gauge section 20 above 99.9% thereby preventing the infiltration of an abrasive ink into the gauge section 20.
