PROBLEM TO BE SOLVED: To shorten the time required for examination by making a minute examination object part which is indistinguishable by only a brightness contrast image, distinguishable even in a low magnification. SOLUTION: The adapter 1 for microscopic observation is disposed between a branch point 11 between illuminating light L<SB>1</SB>and reflected light L<SB>2</SB>of the microscope 8, and an examination object and is constituted by putting two quarter-wave plates 5 and 6 one over the other in a thickness direction and is rotatable about an optical axis, wherein the microscope 8 radiates a linearly polarized light component in a first direction A of the illuminating light L<SB>1</SB>from a light source 9, to the examination object 12 and branches the reflected light L<SB>2</SB>from the examination object 12 from the illuminating light L<SB>1</SB>and observes a linearly polarized light component in a second direction orthogonal to the first direction A, out of the branched reflected light L<SB>2</SB>.
