Abstract: A microelement includes: a base being a body of the microelement, the base including a liquid inlet for a liquid to be introduced, a liquid outlet for the liquid to be discharged, and a groove for the liquid to flow from the liquid inlet toward the liquid outlet; a cover that covers the groove of the base; and a liquid flow controller film segment that is fixed to an inner surface of the cover so as to be opposite to the groove. The liquid flow controller film segment is arc-shaped curved-band-like extending in a direction crossing a flow direction of the liquid and has a radius about a center-corresponding position of the cover corresponding to a center of the liquid outlet of the groove. The liquid flow controller film segment is exposed in the groove and disposed on the downstream side to an exposed surface at the inner surface of the cover in the flow direction of the liquid in the groove. The liquid flow controller film segment has a contact angle that is greater than a contact angle of the exposed surface at the inner surface of the cover.

Abstract translation: 微元件包括：基部，其是微元件的主体，所述基部包括用于待引入的液体的液体入口，用于待排出的液体的液体出口，以及用于液体从液体入口朝向 液体出口 覆盖基部的槽的盖; 以及液体流量控制器膜段，其被固定到所述盖的内表面以与所述凹槽相对。 液体流量控制器膜段是在与液体的流动方向相交的方向上延伸的弧形弯曲带状的，并且具有与盖的液体出口的中心对应的盖的中心对应位置的半径 。 液体流动控制器膜段在凹槽中暴露并且在下游侧沿着凹槽内的液体的流动方向设置在盖的内表面处的暴露表面。 液体流量控制器膜段具有大于在盖的内表面处的暴露表面的接触角的接触角。
