In a honeycomb filter in which a plurality of honeycomb segment bodies are bonded together by a bonded portion, occurrence of cracks in the bonded portion is suppressed. SOLUTION: Two surfaces of the spacer portion 8 facing the honeycomb segment body 1 are in contact with the honeycomb segment body 1. Then, the thermal expansion coefficient αh of the honeycomb segment body 1, the thermal expansion coefficient αs of the joint portion 2, and the thermal expansion coefficient αsp of the spacer portion 8 satisfy αsp>αh> αs or satisfy αsp <αh <αs. .
