A method of producing a ceramic fired body may includes a step of passing a first accommodating shelf through a firing kiln, the first accommodating shelf including a stack of units of a shelf plate and a frame placed on the shelf plate, one or more ceramic bodies placed on the shelf plate being surrounded by the frame extending in a circumferential direction between the shelf plates; a step of retrieving one or more frames from the first accommodating shelf which has passed through the firing kiln; a step of using the one or more retrieved frames to build a second accommodating shelf for passing through the firing kiln; and a step of rotating the retrieved frame such that a rotational position of the retrieved frame when the second accommodating shelf passes through the firing kiln is different from a rotational position of the retrieved frame when the first accommodating shelf passed through the firing kiln.
