An object of the present invention is to provide a detection method capable of detecting contamination of PCB quickly, simply and inexpensively using insulation oil or the like used in a transformer or the like as a test sample. An oily sample is subjected to a treatment including a PCB elution treatment with a nonpolar solvent through a solid phase column, and an anti-PCB antibody is obtained against the elution treatment using the final solvent as a polar solvent. The above-mentioned problem is solved by providing a method for detecting PCBs, wherein the PCB is detected by immunochromatography using the above-mentioned, and the detection result is used as a quantitative or qualitative index for PCBs in the oily sample.
