A laboratory dish comprises an incubation container, containing cultured cells, for observation through a microscope, in which a partitioning member partitions an interior of the incubation container into a plurality of incubation chambers by substantially perpendicular walls. The partitioning member tightly fits to a bottom portion of the incubation container, thereby capable of retaining in separation a liquid inputted in each of the incubation chambers from liquids in the other incubation chambers. A cover member covers an upper portion of each of the incubation chambers partitioned by the partitioning member and tightly fitted to the partitioning member. A whole or part of the cover member is formed of a transparent member, and the upper portion of each incubation chamber is formed with an opening via which to input the liquid.

1. An incubation container, containing cultured cells, for observation through a microscope, comprising: a bottom and a sidewall; a partitioning member water-tightly partitioning an interior of said incubation container into a plurality of incubation chambers by perpendicular walls and water-tightly fitting to or formed integrally with a portion of the bottom of said incubation container, thereby capable of retaining in separation a liquid inputted in each of said incubation chambers from liquids in other incubation chambers; anda cover member covering an upper portion of each of said incubation chambers partitioned by said partitioning member and water-tightly fitted to or formed integrally with said partitioning member, the cover member having an under surface located at a level lower than the top of the sidewall and having an upper surface surrounded by a peripheral wall,wherein a whole or part of said cover member is formed of a transparent member, andthe upper portion of each of said incubation chambers is partly formed with an opening that is not covered by the cover member, via which to input the liquid in each of said incubation chambers. 2. The incubation container according to claim 1, wherein said cover member has a flat portion providing said under surface and a cylindrical edge portion providing said peripheral wall at an outside diametrical portion thereof and is positioned, with said flat portion being directed downward, concentrically with said incubation container in the interior of said incubation container, the outside diametrical portion of said cover member is formed smaller than an inside diametrical portion of said sidewall of said incubation container,said flat portion and said edge portion of said cover member are in contact with said partitioning member,a contact portion therebetween has the water-tightness, andsaid opening is formed between the inside diametrical portion of said sidewall of said incubation container and the outside diametrical portion of said cover member, wherebythe liquids are poured via said opening into said incubation chambers and can fill up between said flat portion of said cover member and the bottom portion of said incubation container. 3. An incubation container, containing cultured cells, for observation through a microscope according to claim 1, further comprising a doughnut-shaped attachable/detachable member covering said opening, wherein said opening is formed between an inside diametrical portion of said sidewall of said incubation container and an outside diametrical portion of said cover member. 4. The incubation container according to claim 2, further comprising a doughnut-shaped attachable/detachable member covering said opening between the inside diametrical portion of said sidewall of said incubation container and the outside diametrical portion of said cover member. 5. An incubation container, containing cultured cells, for observation through a microscope, comprising: a container body for containing said cultured cells, the container body, having formed at a bottom thereof, an aperture;a first cover member that closes said aperture; a partitioning member partitioning an interior of said container body into a plurality of incubation chambers by perpendicular walls and tightly fitting to said cover member, thereby capable of retaining in separation liquid inputted in one of said incubation chambers from liquids in the other incubation chambers;a second cover member covering an upper portion of the incubation chambers partitioned by said partitioning member;said container body, said partitioning member and said second cover member being formed integrally; andsaid second cover member being so sized that an area of the second cover member projected on the bottom of the said container body is smaller than that of said aperture. 6. The incubation container according to claim 5, wherein said first cover member is bonded to an outer surface of the bottom portion of said container body and an lower end surface of said partitioning member. 7. The incubation container according to claim 5, wherein said first cover member comprises a cover made from a glass. 8. The incubation container according to claim 5, wherein said aperture and said second cover member are circular, and satisfying the following condition: d2
