Abstract
A microscope apparatus efficiently supplies and collects a liquid for observation by local liquid immersion. The apparatus includes an objective of a liquid immersion system, a discharging member for discharging the liquid between a front edge of the objective and a substrate, and a sucking member for sucking the liquid. Inclined faces are provided respectively in two positions adjacent to the front edge in the periphery of the objective, and protruded portions are provided in positions adjacent to the inclined faces. An aperture portion bounded by the protruded portions and the substrate is formed at the side face. The discharging member includes a tubular member provided on the inclined face for discharging the liquid. The sucking member includes another tubular member for sucking the liquid while taking in air via the aperture portion.
