On the other hand, it is prepared to embed the embedding resin for each kneaded material. Specifically, for the EpoFix cold-embedded resin (two-liquid mixed type of epoxy resin and curing agent), 3 parts by weight of the curing agent was blended with respect to 25 parts by weight of the epoxy resin to prepare a necessary amount of the embedding resin. Subsequently, the embedding resin was poured into a container in which each kneaded material was accommodated so as to completely submerge the respective kneaded materials. Then, it was allowed to stand at room temperature (about 25 (7:8 to 8 hours) until the resin for embedding was completely cured. Thus, a sample resin in which each kneaded material was embedded was prepared. 9 Subsequently, the sample was sampled. The resin was taken out from the container, and a precision cutting machine (manufactured by BUEHLER Co., Ltd., Is() met) was used, and the n-practice was cut in the center portion of the cut surface to obtain each sample piece (to the extent of 5 to 7 legs) 161I59.doc 201247311 The cut surface of each sample obtained is ground by the following equipment and conditions.
