There is disclosed a plugged honeycomb structure in which a particulate matter hardly remains unburnt in both a circumferential portion and a central portion of a filter, and the number of times to regenerate the filter can be decreased as compared with a conventional plugged honeycomb structure. A plugged honeycomb structure 100 includes a honeycomb structure body 4 of a segmented structure and plugging portions 5 disposed in open ends of cells 2 formed in the honeycomb structure body 4, the honeycomb structure body 4 has outer segments 6b and inner segments 6a disposed on an inner side than the outer segments in a cross section of the honeycomb structure body 4, and a material constituting the outer segments 6b has a smaller heat capacity per unit volume than a material constituting the inner segments 6a.
