Claim Text:
1. An applicator applying microneedles to a skin, the applicator comprising: a transmission member that transmits biasing force of a biasing member to a microneedle array including microneedles with a needle density of 500 needles/cm a mass of the transmission member is 1.5 g or less, the biasing member is an elastic member, the transmission member moves without receiving the biasing force of the elastic member in a first section forming a part of a movement section in which the transmission member moves toward the skin, a momentum of the transmission member activated by the biasing force of the biasing member is from 0.0083 (N·s) to 0.015 (N·s), wherein the applicator further comprises a support base supporting the elastic member and transmits the biasing force to the transmission member in a second section different from the first section, and wherein the support base pushing the transmission member with the biasing force stops at one end of the second section, whereby the transmission member moves without receiving the biasing force in the first section.
