A method for manufacturing a honeycomb structure includes molding a ceramic raw material to manufacture honeycomb molded bodies. The honeycomb molded bodies are fired to manufacture honeycomb fired bodies. End faces of at least two of the honeycomb fired bodies are joined interposing a joining material between the end faces to manufacture honeycomb joined bodies each having a length larger than a length of each honeycomb fired body. Side faces of the honeycomb joined bodies are bonded interposing an adhesive paste between the side faces to manufacture an aggregated body of the honeycomb joined bodies. The adhesive paste is dried and solidified to manufacture a honeycomb block including the aggregated body. The honeycomb block is separated at the joining material into at least two honeycomb blocks.
