Abstract
A honeycomb structure includes a central area and a reinforced outer peripheral area. For a boundary cell having cell walls with different wall thicknesses on two sides parallel with an imaginary parallel line, a thin wall thickness t<a thick wall thickness t, an inner wall thickness t<an outer wall thickness t, t=t, and t=t. The honeycomb structure includes a cross-shaped unit having a thin wall, an inner wall, a cell wall, and a cell wall and a cross-shaped unit having a thick wall, an outer wall, a cell wall, and a cell wall. The honeycomb structure also includes cross-shaped units extending vertically and horizontally from alternate cell vertexes arranged from a cell vertex as a starting point. In the central area and the reinforced outer peripheral area, the cell walls of each cross-shaped unit have a substantially equal wall thickness.
