Abstract
A cell detection device that detects a cell in a specimen with high sensitivity and includes a sealed container having a sealable specimen introduction portion, a culture portion that holds a culture solution, an extraction reagent portion that holds an extraction reagent, and a luminescent reagent portion that holds a luminescent reagent, a contact mechanism that controls contact between the culture solution, the extraction reagent, and the luminescent reagent, a photodetector that detects luminescence from the luminescent reagent portion, and a calculator that determines growth of a cell based on a detection signal of the photodetector. The culture solution, the extraction reagent, and the luminescent reagent are separately disposed in the sealed container, and the contact mechanism brings the culture solution to which a specimen is added and the extraction reagent into contact to obtain an extraction solution, and intermittently brings the extraction solution and the luminescent reagent into contact.
