Abstract

The present invention relates a setting method for a conducting element of an electrochemical test strip and electrochemical test strip thereof. An inspection body is formed by injection molding polymer plastic materials to coat with the plurality of conducting elements, and an external contact surface on an information outputting end of the conducting element is exposed from an inspection slot of the inspection body, so that the information outputting end of the conducting element is extended from the inspection body. Eventually, the information outputting end is bent to fix on a surface of the inspection body. The present invention is not complex and has more precision and convenience, and the manufacturing cost can be reduced efficiently, so that wide application can be expected in the near future.
