| abstract |
The invention provides a method of producing a microneedle. A jig is heated to a temperature above the level at which a temperature-sensitive material that exhibits thermoplastic deformation becomes viscoplastic, the jig is brought into contact with the temperature-sensitive material, and then the jig is pulled part from the temperature-sensitive material to elongate the portion of the temperature-sensitive material in contact with the jig, whereby acicular projections are formed. |
