    Abstract: Provided is a method for manufacturing a plugged honeycomb structure capable of suppressing densification of a trapping layer. A method for manufacturing a plugged honeycomb structure, includes: a forming raw material preparation step of mixing and kneading a partition wall base material raw material at least including cordierite powder and binder with water to obtain a partition wall base material forming raw material; a forming/drying step of forming the obtained partition wall base material forming raw material to obtain a honeycomb formed body, and drying the obtained honeycomb formed body to obtain a honeycomb dried body; a slurry application step of applying trapping layer forming slurry to a surface of a not-fired partition wall base material of the obtained honeycomb dried body; a firing step of firing the honeycomb dried body to which the trapping layer forming slurry has been applied to obtain a honeycomb fired body; and a plugging step of disposing a plugging portion at open ends of predetermined cells of the honeycomb dried body to which the trapping layer forming slurry has been applied or of the honeycomb fired body. The trapping layer forming raw material includes a cordierite forming raw material or alumina.
