A container stock management technique in a hospital and a culture center is provided. A stock management device (1) manages both transfer (outgoing transfer) of cells sampled at the hospital to the culture center, and transfer (incoming transfer) of the cells cultured from the sampled cells at the culture center, to that hospital, with one working code. The ID of containers used individually for the outgoing transfer and the incoming transfer are made to correspond to an identical working code. The optimum transfer route including the procurement of containers is determined by examining the container stock in each of the hospital and the culture center.
