Abstract
A method for producing a needle-shaped body having needles on a first surface of a substrate made of a thermoplastic resin, the method including the steps of: forming the needle-shaped body by filling the thermoplastic resin into a duplication plate having recesses that correspond to shapes of the needles; providing a support member made of a material different from a material for the needle-shaped body on a second surface of the substrate which is opposite to the first surface; and removing the needle-shaped body and the support member which are integrally formed from the duplication plate.

A method for producing a needle-shaped body, the method comprising the steps of:
- filling a melted thermoplastic resin into a duplication plate having recesses having inverted needle shapes;
- applying a support member to a surface of the thermoplastic resin, which is opposite to a surface of the thermoplastic resin facing the duplication plate, wherein the support member is made of a material different from the thermoplastic resin of;
- removing the thermoplastic resin and the support member, which are integrally formed on the duplication plate, from the duplication plate;
- and
- removing the support member from the thermoplastic resin using a solvent in which the material for the support member is soluble, wherein the removed thermoplastic resin forms a needle-shaped body comprising a substrate having a first surface having needles.

- adhering the second surface of the substrate, with the support member removed, to a convex curved surface of a reinforcement layer.
A method for producing a needle-shaped body, the method comprising the steps of:
- filling a melted thermoplastic resin into a duplication plate having recesses having inverted needle shapes;
- applying a support member to a surface of the thermoplastic resin, which is opposite to a surface of the thermoplastic resin facing the duplication plate, wherein the support member is made of a material different from the thermoplastic resin;
- removing the thermoplastic resin and the support member, which are integrally formed on the duplication plate, from the duplication plate;
- and
- removing the support member from the thermoplastic resin, wherein the removed thermoplastic resin forms a needle-shaped body comprising a substrate having a first surface having needles,
- wherein the step of applying the support member is a step of adhering the support member to the thermoplastic resin by using an adhesive having adhesiveness that varies in response to external stimulation or wherein the material of the support member has adhesiveness that varies in response to external stimulation to the thermoplastic material and
- the step of removing the support member from the thermoplastic material comprises applying the external stimulation.
