To provide a honeycomb body which is used in a catalyst carrier converter and has an improved durability.SOLUTION: There is provided a honeycomb body in which a gas conduction path for axially conducting gas is formed by laminating and winding in the axial direction a flat foil and a corrugated foil 30 having an offset structure that includes a large number of cells and in which cells F adjacent to each other in the axial direction have different phases. In the honeycomb body, a first bonding layer 51 for joining the corrugated foil 30 and the flat foil extends in the axial direction while connecting a top surface 101 of a first cell F1 located at the first position from a gas inlet side end in the axial direction and a top surface 101 of a second cell F2 at the second position. It comprises a second bonding layer located at a gas outlet side with respect to the first bonding layer 51. In the honeycomb body, the first bonding layer 51 and the second bonding layer have no overlapping region in the radial direction of the honeycomb body, the first bonding layer 51 is provided on one surface of front or back surface of the flat foil, and the second bonding layer is provided on the other surface of the front or back surface.SELECTED DRAWING: Figure 2 【課題】触媒担持用コンバータに用いられる、耐久性を高めたハニカム体の提供。【解決手段】平箔と多数のセルを含むとともに軸方向に隣接するセルＦの位相が互いに異なるオフセット構造を備えた波箔３０とを積層して軸方向の周りに巻き回すことにより、軸方向にガスを導通させるガス導通路を形成したハニカム体において、波箔３０及び平箔を接合する第１接合層５１は、軸方向におけるガス入側端部から１番目に位置する第１セルＦ１の天面１０１と２番目に位置する第２セルＦ２の天面１０１とを繋いで軸方向に延びているハニカム体。第１接合層５１よりもガス出側に位置する第２接合層を含み、第１接合層５１及び第２接合層は、ハニカム体の径方向において重複する領域がなく、かつ、第１接合層５１は平箔の表面及び裏面のうち一方の面に設けられており、第２接合層は表面及び裏面のうち他方の面に設けられているハニカム体。【選択図】図２
