Manufacturing method of honeycomb structure

A manufacturing method of a honeycomb structure comprising:

• a dry mixing step of dry-mixing raw materials to form the honeycomb structure by a batch treatment,
• a wet mixing step of adding a liquid including at least one selected from the group consisting of water, a surfactant, a lubricant and a plasticizer to a dry mixture obtained in the dry mixing step, to perform wet mixing, wherein the wet mixing step is performed by a batch treatment,
• a kneading step of kneading a wet mixture obtained in the wet mixing step, and
• a forming step of extruding a forming material prepared in the kneading step into a honeycomb structure,
• wherein in the dry mixing step, a used forming material passed through the forming step is added as a part of the raw material, to perform dry mixing, and
• the kneading step includes a liquid re-adding step of further adding the liquid in a process of kneading the wet mixture.
