The present invention provides an electrochemical sensing strip, comprising an electrochemical sensing strip body and an auxiliary support sheet disposed under the electrochemical sensing strip body. Compared to the prior art, the electrochemical sensing strip provided in the present invention has an auxiliary support sheet, which functions to support the electrochemical sensing strip body, so that the entire electrochemical sensing strip does not deform easily. Consequently, the resistance to bending of the electrochemical sensing strip is enhanced, and the occurrence of bending the electrochemical sensing strip during operation is reduced, and thus the test error of the electrochemical sensing strip is reduced.
