1. An electrically heating support, comprising:
a ceramic honeycomb structure, the honeycomb structure comprising an outer peripheral wall and a partition wall arranged on an inner side of the outer peripheral wall, the partition wall defining a plurality of cells each extending from one end face to the other end face to form a flow path; and
a pair of metal electrodes for applying a voltage to the honeycomb structure,
wherein each metal electrode of the pair of metal electrodes comprises:
at least one connection portion fixed to an outer peripheral surface of the honeycomb structure;
at least one drawer portion extending from the at least one connection portion, and
wherein the at least one drawer portion is provided with at least two bent portions, and extending directions of ridgelines of the at least two bent portions are different from each other and include a first direction parallel to an axial direction of the honeycomb structure and a second direction orthogonal to the first direction.
