Provided is a conductive resin composition for microwave heating capable of suppressing the generation of sparks when microwave heating is performed. A conductive resin composition for microwave heating comprising a non-carbonaceous conductive filler, a curable and insulating binder resin, and a carbonaceous material having a higher volume resistivity value than the non-carbonaceous conductive filler, the carbonaceous material having an aspect ratio of 20 or less, and the content of the carbonaceous material being 1 to 20 parts by mass, relative to the total of 100 parts by mass of the non-carbonaceous conductive filler and the curable and insulating binder resin. The carbonaceous material efficiently absorbs the microwave, and thus, when the microwave is irradiated to heat and cure the conductive resin composition, generation of sparks can be suppressed.
