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.
