Abstract
An administration instrument includes an injection button which can be pressed at an angle that is not parallel to a needle with respect to a direction in which the needle is inserted into skin. As a result, it is possible to prevent a force of pressing the injection button from being transmitted in the direction in which the needle is inserted into the skin deeper than initial insertion of the needle, thereby achieving an administration under a stable state.
