PROBLEM TO BE SOLVED: To prevent contamination by powder dust and bacteria. SOLUTION: A chamber 4 for cell culture is formed at the lower position on one surface of a base plate 2, and an introduction passage 10 and a draining passage 12 are formed in meander shapes so that an entrance 6 formed at a position having an opening at one end face present at the reverse side of the chamber 4 for the cell culture, and an outlet 8 may be connected with the chamber 4 for the cell culture. A cover plate 14 is joined to a face on which passages 10, 12, and the like, of the base plate 2 are formed to form a chip-shaped cell-culturing device having the chamber 4 for the cell culture, and the passages 10 and 12 in the inside. The introduction passage 10 and the draining passage 12 have bent parts convexly bent in the lower direction formed by the meandering to capture the powder dust and the bacteria invaded from the entrance 6 and the outlet 8 at the lower part of the bent parts.
