PROBLEM TO BE SOLVED: To provide a method for driving a microprobe in a microfluidic chip which has a high drive frequency, and easily configured.SOLUTION: Not only a pair of a first parallel frame part 40 and a second parallel frame part 42, or the first parallel frame part 40, a third parallel frame part 44 and a pair of connected frame parts 50, 52 are integrally configured, microprobes 16, 60 are connected to the pair of connected frame parts 50, 52 via linear movable frame parts 54, 56 or 64, 66 making a pair, and a microfluidic chip body 30 is configured within one plane, so that high drive frequency is obtained regarding the drive of the microprobes 16, 60. Further, there is no increase in the number of components and complex assembly, and downsizing and lower price of a measurement device 10 are made possible.SELECTED DRAWING: Figure 3 【課題】駆動周波数が高く、しかも簡単に構成される、マイクロ流体チップ内のマイクロプローブの駆動方法を提供する。【解決手段】一対の第１平行フレーム部４０と第２平行フレーム部４２、或いは第１平行フレーム部４０と第３平行フレーム部４４および一対の連結フレーム部５０、５２が一体に構成されるだけでなく、その一対の連結フレーム部５０、５２には、マイクロプローブ１６、６０が対を成す直線状の可動フレーム部５４、５６、又は６４、６６を介して連結されていて、マイクロ流体チップ本体３０が１平面内で構成されるので、マイクロプローブ１６、６０の駆動について高い駆動周波数が得られる。また、部品点数の増加や組み立ての煩雑化がなく、計測装置１０の小型化や低価格化が可能となる。【選択図】図３
