<p>PURPOSE:To prevent superoposition of lattices throughout a multilayer and to uniformize the density state in a peripheral direction of each part, in an adhesion collection type exhaust gas filter wherein a lattice-form metallic sheet is wound in a cylindrical shape and exhaust gas is caused to flow from an inner periphery to an outer periphery. CONSTITUTION:A lattice-form metallic sheet 8 of which a cylindrical filter element 6 is composed is formed in a continuous belt-like shape and has a lattice in a specified shape. Provided the thickness of the lattice-form metallic sheet 8 is (t) and a distance between the lattices along a peripheral direction is (x), 2 pit/x is a value being not an integer.</p> |
