The present invention relates to an apparatus for inducing absorption of drug, which comprises a main body having an accommodation space therein, and the upper end to be able to open a driving motor installed in the accommodation space in the main body, and driven by a rechargeable battery a cam unit connected to the driving motor and converting the rotational motion of the driving motor into the linear motion toward the longitudinal direction of the main body a movable member connected to the cam unit, moving in the longitudinal direction of the main body and having the end positioned to the open upper end of the main body and a needle member installed on the end of the movable member, and having multiple needles formed across the whole region in the longitudinal direction of the main body, wherein the cam unit comprises a housing installed at the upper part of the driving motor a driving cam connected to the driving motor, installed within the housing to be rotatable, and having the upper end formed to be inclined a vertically moving cam installed within the housing, and having the lower surface installed to contact to the upper surface of the driving cam and to be inclined and a plunger formed to be extended to the upper part of the housing from the upper end of the vertically moving cam, and contacting the movable member. According to the present invention, micro holes are formed on the skin by linearly moving the needle member by the cam unit converting the rotational motion of the driving motor into the linear motion, thereby penetrating the drug into the skin through the micro holes, and increasing the procedure effect of the drug.COPYRIGHT KIPO 2015본 발명은 내부에 수용 공간이 형성되고, 상단이 개구되는 본체 상기 본체의 내부 수용 공간에 설치되어 충전식 배터리에 의해 구동되는 구동 모터 상기 구동 모터에 연결되어 구동 모터의 회전 운동을 상기 본체의 길이 방향에 대한 선형 운동으로 변형시키는 캠 유닛 상기 캠 유닛에 연결되어 상기 본체의 길이 방향으로 이동되되, 단부가 상기 본체의 개구된 상단에 위치되는 이동 부재 및 상기 이동 부재의 단부에 설치되되, 전 영역에 걸쳐 복수 개의 니들이 상기 본체의 길이 방향으로 형성되는 니들 부재를 포함하되,상기 캠 유닛은, 상기 구동 모터의 상부에 설치되는 하우징
