The present invention relates to a high-frequency apparatus capable of selectively adjusting a skin penetration depth using a magnetic field, and more specifically, to a high-frequency apparatus including: an electrode module (100) including an electrode pair having a positive electrode and a negative electrode, in which a high-frequency current flows in the electrode pair； and a magnetic field generating module (200) disposed at a location perpendicular to the electrode pair located inside the electrode module (100), for generating the magnetic field, wherein the magnetic field is generated through the magnetic field generating module (200), so that force applied to the high-frequency current flowing in the electrode pair heads for the inside of a skin by Flemings left hand rule so as to allow the high-frequency current to flow inside the skin. According to the high-frequency apparatus capable of selectively adjusting the skin penetration depth using the magnetic field as proposed in the present invention, the magnetic field is generated at a location perpendicular to the flowing direction of the high-frequency current to allow the force applied to the high-frequency current to head for the inside of the skin by the Flemings left hand rule, so that the high-frequency current flows further inside the skin to heat the skin up to a dermis layer of the skin. In addition, according to the present invention, intensity of the high-frequency current and intensity of the magnetic field are adjusted to control magnitude of the force applied to the high-frequency current, so that the depth of the skin into which the high-frequency current penetrates is selectively adjusted.본 발명은 자기장을 이용하여 피부 침투 깊이의 선택적 조절이 가능한 고주파 장치에 관한 것으로서, 보다 구체적으로는 (+)전극 및 (-)전극으로 이루어지는 전극 쌍을 포함하며, 상기 전극 쌍 내에 고주파 전류가 흐르는 전극 모듈(100), 및 상기 전극 모듈(100) 내에 위치한 전극 쌍과 직교되는 위치에 배치되며, 자기장을 생성하는 자기장 생성 모듈(200)을 포함하되, 상기 자기장 생성 모듈(200)을 통해 자기장을 생성하여, 상기 전극 쌍 내에 흐르는 고주파 전류에 작용하는 힘이 플레밍의 왼손 법칙에 의해 피부 안쪽으로 향하도록 해서, 고주
