Abstract

PURPOSE:To make correct evaluation by laminating powder on a dividable substrate surface then dividing this substrate thereby permitting the observation of the section of the powder laminate in the deposited state. CONSTITUTION:A substrate 11 constituted dividably is divided to two with its section in the shape of U. The end faces 13 of the divided substrates 11A, 11B are roughly perpendicular to the top surface 12 of a plane shape, and the divided substrates 11A, 11B are so made so to be easily fixed to one piece. If an electron radiative material is deposited by spraying on the top surface of the integrated substrate 11 to form laminate, and the substrate is divided to two after this, the laminate 14 is parted to expose a section 14A. Thereby, how the powder as the electron radiation material is deposited is observed extremely accurately, and the correct evaluation is accomplished.
