Imaging is performed with a regulation plate having a multitude of fine through holes penetrating in a vertical direction placed between an illuminator for emitting diffused light and a well plate for carrying biological specimens serving as an imaging object in wells. Inner wall surfaces of the through holes are blackened to suppress light reflectance to be low and an image with good contrast is obtained by irradiating only light incident at a small incident angle on the regulation plate to the wells.
