Abstract

See full text

A microneedle array to be used instead of a syringe has, at a tip side of each microneedle, two or four puncture portions disposed facing each other. The puncture portions each have a part of a side surface of each microneedle as outer surfaces, respectively, and one of the puncture portions is shorter than the other(s). A housing section capable of holding a drug is formed by inner surfaces of the puncture portions of each microneedle. The housing section opens toward the tip side and lateral directions orthogonal to an axis core of each microneedle, and has a central bottom surface at a bottom end. The inner surfaces facing each other and forming the housing section of each microneedle each have a downward slope, with a width between the inner surfaces getting narrower as it goes down from tips of the respective puncture portions toward the central bottom surface.
