To provide a heater element with which it is possible to suppress the degradation of a functional material or the breakage of a honeycomb structure.SOLUTION: Provided is a heater element comprising a honeycomb structure 10 in which a bulkhead 14 is composed of a material having PTC characteristic, a pair of electrodes 20a, 20b that are provided to a first end face 12a and a second end face 12b, and a terminal 30 that is provided to at least some of the pair of electrodes 20a, 20b. When it is assumed that ρ1 represents the specific volume resistance [Ω-cm] of the pair of electrodes 20a, 20b, t1 represents the thickness [mm] of the pair of electrodes 20a, 20b, ρ2 represents the specific volume resistance [Ω-cm] of the bulkhead 14, t2 represents the thickness [mm] of the bulkhead 14, ρ3 represents the specific volume resistance [Ω-cm] of the terminal 30, and t3 represents the thickness [mm] of the terminal 30, then (ρ1/t1)/(ρ2/t2) is smaller than or equal to 0.003, and (ρ1/t1)/(ρ3/t3) is greater than or equal to 0.02.SELECTED DRAWING: Figure 1A
