Fluid feed and a fluid monitoring apparatus

PROBLEM TO BE SOLVED: To provide a fluid supply device and a fluid observation device which is used for detecting microorganisms such as yeast and can be integrated and miniaturized.SOLUTION: The present invention relates to a microorganism detection device 1 including the fluid supply device and the fluid observation device that arranges a substrate 2, a syringe 3, and an optical microscope 4 in proximity to each other in a common housing 5, and is provided with: a support part 24 for supporting the substrate 2; a support part 33 for supporting the syringe 3 for supplying a sample liquid to a groove part of the substrate 2 supported by the support part 24; and a support part 41 for supporting the optical microscope 4 for observing the sample liquid passing through the groove part of the substrate 2, wherein the support part 33 supports the syringe 3 so that the syringe 3 is arranged alongside the optical microscope 4 at a position close to the substrate 2 held by the support part 24.SELECTED DRAWING: Figure 2
