Abstract
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.

A holding jig holding a pillar-like body, which 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,
- wherein 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 the inner peripheral surface of the tubular expansion/contraction member is smaller than a surface configuration of the pillar-like body to be held, and
- the configuration of the inner peripheral surface of the tubular jig base member is larger than the surface configuration of the pillar-like body to be held, and
- wherein the inner peripheral surface of the tubular jig base member is provided with a groove along the whole periphery, and
