1. A pillar shaped honeycomb structure for induction heating, the honeycomb structure being made of ceramics and comprising:
an outer peripheral wall; and
a partition wall disposed on an inner side of the outer peripheral wall, the partition wall defining a plurality of cells, each of the cells penetrating from one end face to other end face to form a flow path,
wherein a composite material comprising a conductor and a non-conductor is provided in the cells in a region of 50% or less of the total length of the honeycomb structure from one end face, and
wherein the conductor is a conductor that generates heat in response to a change in a magnetic field.
