1. A honeycomb structure, comprising:
a plurality of honeycomb segments with a porous partition wall that defines a plurality of cells extending from an inflow end face as one end face to an outflow end face as another end face and becoming channels for a fluid; and a bonding layer that bonds side surfaces of the plurality of honeycomb segments one another, wherein the bonding layer contains a plurality of plate-shaped particles, the plate-shaped particles are laminated in a thickness direction of the bonding layer at a cross section of the bonding layer cut off to the thickness direction of the bonding layer, and when assuming a longitudinal scanning line as a scanning line at a length of 1000 μm parallel to the thickness direction of the bonding layer at the cross section of the bonding layer cut off to the thickness direction of the bonding layer, when assuming that the number of plate-shaped particles that form an angle of 45° or more with the longitudinal scanning line is set as the number of particles α among the plate-shaped particles intersecting with the longitudinal scanning line, and a lateral scanning line is a scanning line at a length of 1000 μm perpendicular to the thickness direction of the bonding layer at the cross section, and when the number of plate-shaped particles that form an angle of 45° or more with the lateral scanning line is set as the number of particles β among the plate-shaped particles intersecting with the lateral scanning line, the number of particles α meets Expression: the number of particles α>10, and the number of particles α and the number of particles β meet a relationship of Expression: (the number of particles α/the number of particles β)>3. |
