An imaging apparatus includes an illumination light source emitting illumination light, a small-diameter image-transmitting portion, a distal end of which is placed near a specimen, an objective lens converging the illumination light to a proximal end of the image-transmitting portion, a light-detecting portion that detects light returned from the specimen via the image-transmitting portion and the objective lens, and a shield portion partially blocking the illumination light, the shield portion being disposed at near a pupil position of the objective lens or near a position optically conjugate with the pupil position so as to cover the illumination light path on one side in a radial direction. With this configuration, a sharp image with low noise can be obtained by preventing the occurrence of reflection at the proximal end of the image-transmitting portion and also by avoiding autofluorescene from being produced.
