To provide a DNA chip capable of increasing the number of detectable genes even when a smaller base plate is used.SOLUTION: The base sequence detection chip has plural first electrode groups which are disposed being separated away from each other on a base plate, and each of the first electrode groups includes plural first electrodes which are disposed being separated from each other. Each of the first electrodes has a planar shape like a race track or oval. The plural first electrodes in each of the first electrode groups are disposed with the major axes which are parallel to each other. The base sequence detection chip also has probes which are disposed corresponding to the first electrodes being fixed to the corresponding first electrodes and has a base sequence.SELECTED DRAWING: Figure 7 【課題】より小さな基板を用いても検出可能な遺伝子数を多くすることのできるＤＮＡチップを提供する。【解決手段】本実施形態の塩基配列検出チップは、基板上に互いに離間して設けられた複数の第１電極群であって、各第１電極群は離間して配置された複数の第１電極を有し、各第１電極はレーストラックまたは楕円の平面形状を有し、各第１電極群内の前記複数の第１電極は長軸が互いに平行となるように並列して配置される、複数の第１電極群と、各第１電極に対応して設けられ、対応する第１電極に固定され、塩基配列を有するプローブと、を備えている。【選択図】図７
