摘要： There is disclosed a honeycomb structure. A honeycomb structure includes a pillar-shaped honeycomb structure body having partition walls defining a plurality of cells which become through channels for a fluid and extend from a first end face to a second end face, the partition walls are constituted of a porous body having aggregates and a bonding material to bond the aggregates to one another in a state where pores are formed among the aggregates, the aggregates include molten silica particles, the bonding material includes glass, a content ratio of SiO2 in the porous body is 70 mass % or more, and a thermal expansion coefficient of the porous body at 40 to 800° C. is from 1.5 to 6.0×10−6/° C.

摘要： A microwave drying method includes: an introduction step of disposing a honeycomb formed body while keeping an axis direction X of cells of the honeycomb formed body vertically and introducing the honeycomb formed body into a drying furnace capable of irradiating with microwaves; a reflector placing step of placing a microwave reflector having a function to reflect the microwaves above and/or below around the honeycomb formed body; and a microwave drying step of irradiating with the microwaves while controlling temperature of an inside of the honeycomb formed body by the microwave reflector so that any one of the end faces (e.g., end face) of the honeycomb formed body reaches 100° C. to dry the honeycomb formed body after the other part of the honeycomb formed body reaches 100° C.
