Cell culture device

A cell culture device comprising:

• a housing in which a plurality of through-holes are formed in at least one surface to allow carbon dioxide to enter from the outside and which has an inner space filled with a culture medium for cell culture;
• a plurality of support bodies which are disposed in multiple stages at predetermined intervals from each other in the inner space for cell culture, which are provided in the shape of a plate having a predetermined area;
• and
• a porous member which is attached to one surface of the housing to cover the plurality of through-holes and is configured to prevent external leakage of the culture medium filled in the inner space and allow carbon dioxide to enter the inner space from the outside, and
• wherein the plurality of support bodies maintain a state in which two support bodies adjacent to each other are spaced apart via a spacer disposed in the inner space,
• wherein the spacer includes a first guide member and a second guide member, which are inserted into the inner space so that one surface of the first guide member and one surface of the second guide member face each other, and a third guide member disposed at a central portion of the inner space,
• wherein the first guide member and the second guide member include a first plurality of slot grooves formed to be recessed in a longitudinal direction,
• wherein both surfaces of the third guide member respectively face one surface of the first guide member and one surface of the second guide member, and a second plurality of slot grooves is formed to be recessed in the longitudinal direction in each of both surfaces of the third guide member,
• wherein the plurality of support bodies are mounted in the multiple stages by being inserted into the first plurality of slot grooves and the second plurality of slot grooves.
