The invention discloses a reference electrode based on a microfluidic technology, and relates to the field of reference electrodes. The reference electrode comprises a main liquid path and branch liquid paths communicated with the main liquid path, the reference electrode is arranged in the branch liquid paths, an air hole is formed in the tail end of the branch liquid paths, and an anti-overflow filter element is arranged in the air hole. The calibration liquid in the main liquid path simultaneously flows into the branch liquid paths, the anti-overflow filter elements at the tail ends of the branch liquid paths are closed and airtight after meeting water, the calibration liquid stops flowing, and the calibration liquid can be prevented from flowing out of the card and entering the instrument. The problem that in the prior art, the reference electrode is complex to manufacture is solved. The effects that the reference electrode is easy to manufacture and the measured potential is accurate are achieved. 本发明公开了
