PROBLEM TO BE SOLVED: To provide a sample object constitution member capable of constituting the sample object with which the reflection on an undesirable surface of detection light of an autofocusing device is suppressed. SOLUTION: The pinch sample object 110 is comprised of slide glass 120, cover glass 130, and a sample 140 held between the slide glass 120 and the cover glass 130. The sample 140 consists of, for example, an observation object 142, and an encapsulating medium 144, such as glycerol, and has a refractive index of approximately 1.3 to 1.55. The slide glass 120 is subjected to a visible light reflection preventive/near IR light reflective coat 124 on a sample holding surface 120a touching a top surface, i.e., the sample 140. The visible light reflection preventive/near IR light reflective coat 124 has low reflectivity to light of a visible region and high reflectivity to light of a near IR region with respect to the sample 140 of the refractive index of approximately 1.3 to 1.55.
