PROBLEM TO BE SOLVED: To provide a substrate with a satisfactory manufacture yield and suitable for use as a substrate for microscopic observation. SOLUTION: A glass plate of high surface flatness is employed in stead of natural mica so far used as a base material. A break groove is formed in advance in one surface of the glass plate of an S grade, and thereafter, a gold thin film is formed by vapor deposition on the reverse surface. A substrate for specimen observation of a scanning probe microscope or a substrate, of 10 mm square for example, suitable for a reflector for reflectance spectrum analysis, is cut out by only applying a small amount of force to the break groove by means of a pair of tweezers, etc. The substrate thus obtained is resistant to exfoliation, etc. of the gold thin film, easy to handle, excellent in durability and corrosion resistance, and free from slowly releasing humidity like mica. This substrate is used for forming a suitable specimen observation substrate, etc. COPYRIGHT: (C)2006,JPO&NCIPI
