Honeycomb structure and method for manufacturing honeycomb structure

A honeycomb structure comprising:

• a plurality of pillar-shaped honeycomb segments each having a porous partition wall defining a plurality of cells that extend from a first end face as one end face to a second end face as the other end face and that serve as a channel of a fluid;
• and
• a porous bonding layer containing a crystalline anisotropic ceramic and disposed so as to bond side surfaces of the plurality of honeycomb segments to each other, wherein
• a pore having a pore diameter of 10 μm or more and less than 50 μm in a pore distribution of the bonding layer is defined as a fine pore, and a pore having a pore diameter of 50 μm or more and 300 μm or less in a pore distribution of the bonding layer is defined as a coarse pore,
• a ratio of a pore volume (cc/g) of the fine pore with respect to a pore volume (cc/g) of the coarse pore is from 2.0 to 3.5,
• the pore volume of the fine pore is from 0.15 to 0.4 cc/g, and
• the pore volume of the coarse pore is from 0.05 to 0.25 cc/g.
