Inner cells (30) and outer cells (30) which are adjacent to one another in a radial direction of a main body (21) are arranged offset from one another, and therefore adequate strength with respect to compressive forces and tensile forces can be obtained without significant thermal expansion or contraction in the radial direction, even if the temperature rises or falls suddenly. Further, because the inner cells (30) and the outer cells (30) are disposed offset from one another, a minimum radial direction pathway length (R1) from the center (23) of the main body (21) to an outer wall (22) thereof via circular arc walls (31, 32) and straight-line walls (33, 34) is greater than an outer shell radial dimension (R2) of the main body (21). The electrical pathway is therefore increased, and this configuration can therefore be suitably used in an exhaust gas purifying device (10A), for example. |
