PROBLEM TO BE SOLVED: To provide a heating electrode device having a high output and less visible by efficiently increasing a cross-sectional area of a heating conductor while suppressing increase in a width of the conductor.SOLUTION: The heating electrode device includes a plurality of heating conductors 22 each having a square cross section, extending in one direction, and arranged in a direction different from the extension direction. In a cross section orthogonal to the extension direction, the heating conductor satisfies H/W≤1.0, where H represents a thickness of the conductor that is a size in a direction orthogonal to the arrangement direction, and Wis a size of a larger side in the sides parallel to the arrangement direction. The heating conductors are arranged at a pitch P along a direction where a bus bar electrode extends. The pitch P and a surface area Sof the heating conductor per 0.01 m length in a plan view of one surface in the thickness direction of the heating conductor, and a surface area Sper 0.01 m length in a plan view of the other surface opposite to the one surface satisfy 0.5 mm≤P≤5.00 mm and 0 μm
