To provide a production method of a base metal catalyst for exhaust gas purification and with a catalyst activity, in which a base metal-supported catalyst is uniformly supported by a honeycomb substrate. A production method of a catalyst for exhaust gas purification, comprising the steps of preparing a honeycomb substrate having a plurality of cells, preparing a base metal-supported catalyst comprising a carrier supporting a metal containing a base metal having an exhaust gas purification performance, preparing a slurry having a pH of 7 or more by dispersing the base metal-supported catalyst in an aqueous solution, and introducing the slurry to a partition wall surface of the honeycomb substrate. |
