Microneedle structure and method for producing same

Abstract

Microneedle structure of the present invention includes a needle-shaped portion on one surface side of a base material. The base material has fluid permeability in its thickness direction. The needle-shaped portion is composed of a composition that contains a low-melting-point resin having a melting point of 150° C. or lower. The needle-shaped portion has a surface and an interior that are formed with hole portions. The method for producing a microneedle structure of the present invention includes a bonding step of heating a composition containing a low-melting-point resin having a melting point of 150° C. or lower to bond the heated low-melting-point resin and the base material. Thus, the microneedle structure and the method for producing the microneedle structure are provided, in which the influence of high temperature on the base material is reduced and the degree of freedom in selecting the base material is high.
