A three-dimensional bioelectrochemical sensor strip structure includes a pair of insulating substrates, a transparent reacting area disposed at an end of the substrates, an opening disposed around the periphery of the reacting area, an electrode having an operating electrode and a reference electrode of different polarities disposed between the substrates, a spacer disposed between the electrodes, and a hydrophilic enzyme covered onto an end of the electrode facing the substrate. When a test is performed, an end of the electrode not covered by the hydrophilic enzyme is inserted into the sensing machine, and the testing object (such as blood) is dripped into any position of the opening of the reacting area, such that the enzyme is dissolved quickly. With the spacer, the electrodes at both sides of the spacer provide a guide of a channel, and a dedicated biochemical reaction is conducted between the oxidation-reduction substance and the test object to produce an electron transfer. The concentration of the testing object can be detected by the sensing machine. The hydrophilic enzyme on the electrode allows the testing object to be absorbed into the reacting area easily, and the direction of the opening of the reacting area is not restricted, and thus facilitating the testing object to enter into the reacting area.
