PROBLEM TO BE SOLVED: To manufacture a sample plate at low cost with ease which holds a plurality of samples at the same time. SOLUTION: A metal film 3 is allocated on a transparent substrate 2, a hydrophilic coupling-reactive film 4 is formed on the metal film 3, further, a hydrophobic negative photo-resist 5 is allocated on the coupling-reactive film 4, and the photo-resist 5 is exposed with a mask 7 of specified pattern and then developed so that the photo-resist 5 is specifically patterned, for forming a sample plate. Such part, after development, surrounded with a hydrophobic film 5a of a remaining photo-resist and a hydrophilic coupling-reactive film 4 is taken as a sample holding part 6.
