PROBLEM TO BE SOLVED: To more easily form electrode portions and further to reduce volume resistivity.;SOLUTION: A honeycomb structure 20 includes a partition portion 22 constituting a plurality of cells 23 serving as flow paths of a fluid. This honeycomb structure 20 further includes: electrode portions 32 which are disposed as parts of the partition portion 22 and which have an SiC phase, an oxide phase containing an Si oxide, an Al oxide, and an alkaline-earth metal oxide, and a metal phase containing metal Si and metal Al, where the proportion of metal Al relative to the total amount of metal Si and metal Al is 0.001-20 mol%; and a heat generation portion 34 which is a part of the partition portion 22 and which has a volume resistivity higher than that of the electrode portion 32. This honeycomb structure is obtained by forming an impregnation base material containing metal Si and metal Al and an alkaline-earth metal compound on a part of the surface of a honeycomb base material having an SiC phase and an oxide phase containing an Si oxide and impregnating metal Si and metal Al into pores of the honeycomb base material through heating in an inert atmosphere.;COPYRIGHT: (C)2013,JPO&INPIT
