PROBLEM TO BE SOLVED: To reduce the influence of heat shock stress on cells which are samples temporarily stored inside a pass box. SOLUTION: The sample storage device of the present invention has a main body having at least a mounting table on which a culture container in which cells are cultured is placed, and a storage space provided above the mounting table, and an air conditioner. The final dust removing means for finally removing dust from the air sent by the blower of the air conditioner to capture the microorganisms and introducing them into the storage space, and the heating that is located directly above the final dust removing means and heats the air from the air conditioner. It has a means and a humidifying means having a nozzle protruding into a space on the upstream side of the final dust removing means on the downstream side of the heating means and humidifying the air sent through the heating means, and is supplied from the air conditioner. An opening that is installed side by side on the side of a safety cabinet that has a work space inside and that allows the storage space and the work space to communicate from the side of the safety cabinet. It is characterized by having a door that closes the opening.
