PROBLEM TO BE SOLVED: To automatically set up a fold of an unfilled part of a conventional bag-filled culture medium block, thereby automating a series of steps of producing a bed block by inoculating a culture medium with inoculum. Provided are a fungal bed block manufacturing apparatus and a manufacturing method having an unfilled part standing mechanism. A bag body having a bottom surface and a bag mouth facing the bottom surface, a filling portion filled with a medium 12 of the bag body, and an unfilled portion 11h from the filling portion to the bag mouth, A fungal bed block manufacturing apparatus 20 for producing a fungal bed block 17 in which a seed culture 13 is inoculated into a medium 12 from a packed medium block 14 in which a filled portion 11h is folded, and a folded unfilled portion 11h is provided upright. The unfilled portion standing mechanism 33 for opening, the standing unfilled portion 11h are opened, and the opening inoculation mechanism 45 for inoculating the inoculum 13 from the bag mouth side of the unfilled portion 11h and the unfilled portion 11h are sealed. The sealing mechanism 52 is provided.
