    摘要: An object of the invention is to provide composite particles that have excellent NOx purification performance and can suppress water adsorption-caused contraction and water desorption-caused expansion and to provide a honeycomb structure that has excellent NOx purification performance and can suppress the breakage of the honeycomb unit due to the adsorption or desorption of water, a method for manufacturing the honeycomb structure, and an exhaust gas purifying apparatus including the honeycomb structure. The composite particles of the invention are composite particles having a metallic oxide attached to silicoaluminophosphate particles with a ratio of an amount of Si to a sum of amounts of Al and P in a range of 0.16 to 0.33, in which a specific surface area is in a range of 250 m 2 /g to 450 m 2 /g, and an external surface area is in a range of 30 m 2 /g to 90 m 2 /g.
