PROBLEM TO BE SOLVED: To provide an injector capable of intracorporeally injecting injection liquid in a place of an appropriate depth of a skin.SOLUTION: An injector includes a microneedle device having, for example, a protrusion on one surface of a base plate and a microneedle penetrating the base plate and the protrusion, and a support medium. The injector is characterized by the fact that it has an adjustment mechanism to adjust a projection height of the protrusion from the surface of the support medium to a predetermined height, e.g. 0.1-3.0 mm, and adjust a dial in the level of 3-10.SELECTED DRAWING: Figure 1 |
