Abstract
A method for manufacturing a microprojection unit () according to the invention involves: a microprojection tool forming step of forming a microprojection tool () by bringing a projecting mold part () into contact from one surface (D) side of a base sheet (A) including a thermoplastic resin, and thus forming a protrusion () that protrudes from another surface (U) side, and withdrawing the projecting mold part () from the interior of the protrusion (); a joining step of joining the one surface (D) side of the base sheet (A), in which the microprojection tool () has been formed, and a tip end of a base component (); and a cutting step of cutting the base sheet (A), to which the base component () has been joined, along a contour (L) of the base component () at a position more inward than the base component's contour (L) in a planar view of the base sheet (A) as viewed from the microprojection tool () side, to manufacture a microprojection unit ().
