Abstract: In a method of manufacturing a honeycomb structured body, a ceramic block is formed by binding multiple pillar-shaped honeycomb fired bodies with adhesive layers interposed therebetween. The multiple pillar-shaped honeycomb fired bodies are bound on a support by piling up the multiple pillar-shaped honeycomb fired bodies successively. A placing position where a primary honeycomb fired body is to be placed is determined. A position of an end face of at least one secondary honeycomb fired body is fixed by applying force to the end face of the at least one secondary honeycomb fired body. The primary honeycomb fired body is placed on the placing position with the position of the end face of the at least one secondary honeycomb fired body being fixed. The fixing further includes first positioning or second positioning based on a number of the at least one secondary honeycomb fired body before the fixing.

Abstract: A honeycomb structure includes honeycomb fired bodies, adhesive layers, and edge members. Each of the honeycomb fired bodies has a first end face, a second end face, and side faces. The adhesive layers are disposed on the side faces to bond the honeycomb fired bodies to each other. Each of the side faces has a first side that is one side of one of the first end face and the second end face. The edge members are disposed on the side faces and including an inorganic material. Each of the edge members has a substantially quadrangular pillar shape with a second side that has substantially a same width as the first side and that is disposed such that the second side is in a vicinity of one of the first end face and the second end face.

Abstract: A sealing material for a honeycomb structure includes inorganic fibers, inorganic particles, and an ion adsorbent. The inorganic fibers include a biosoluble inorganic compound. The ion adsorbent is in an amount of about 0.1% by weight or more.

Abstract: A sealing material for a honeycomb structure includes inorganic fibers, an oxide sol, inorganic particles, and a metal-containing material. The inorganic fibers include a biosoluble inorganic compound. The metal-containing material contains at least one of Mg, Ca, and Sr. The sealing material is acidic.
