Abstract: Provided is a bio chip structure for a comparative experiment. The bio chip structure for a comparative experiment according to the present invention may include: a first pillar substrate including at least one first pillar where a first sample is disposed; a second pillar substrate including at least one second pillar where a second sample is disposed; and a well substrate including wells to which at least one pair of the first pillars of the first pillar substrate and the second pillar of the second pillar substrate is inserted. Accordingly, a comparative experiment to culture a different kind of samples may be conducted in an identical environment, a different kind of samples, which are the subjects of a comparative experiment, may be rapidly and accurately disposed on a plurality of pillars, and an experimental group or a control group may be easily replaced.
