A method for manufacturing a porous body includes a structure forming step that is repeatedly performed a plurality of times and includes: a pore-forming material placing step of placing a pore-forming materialfor forming pores in the porous body; an aggregate placing step of placing aggregate particleswhich are part of raw materials of the porous body; a binder placing step of placing binder particleswhich are part of the raw materials of the porous body; and a binding step of heat-fusing at least part of the placed binder particlesto bind aggregate particlestogether.

Method and apparatus for manufacturing porous body

A holding jig has a tubular jig base member, and a tubular expansion/contraction member disposed on an inner peripheral surface side of the tubular jig base member. Both end sides of the tubular expansion/contraction member are fixed to both end sides of the tubular jig base member along the whole periphery. A configuration of an inner peripheral surface of the tubular expansion/contraction member is smaller than a surface configuration of a pillar-like body (a honeycomb structure) to be held. On the other hand, a configuration of an inner peripheral surface of the tubular jig base member is larger than the surface configuration of the pillar-like body (the honeycomb structure) to be held.
