Abstract
A microneedle includes a base having a support surface, and a projection that protrudes from the support surface, the projection having a through hole that penetrates the projection in an extending direction of the projection. The projection includes a flow path expansion section which is configured to expand a communication path that communicates between an inner space of the through hole and a space surrounding the projection in response to an increase in pressure of a fluid flowing in the through hole.
