The present invention relates to a portable fishing line cutter comprising: first and second support plates disposed to allow one surface to face with each other； a cutter fixed in the first support plate by a cutter fixing part to install a blade to face the second support plate； and an elastic connection part interconnecting the first and second support plates to allow the cutter to be spaced apart from the second support plate, deformed to allow the first support plate to move from the second support plate in the longitudinal direction of the cutter when a force is applied to make the first and second support plates close to each other, so as to allow the cutter to cut a fishing line disposed between the second plate and the cutter, and returning the first and second support plates to allow the first cutter to be spaced apart from the second support plate when the force is removed. Accordingly, while a compact structure is formed by a totally plate-shaped structure and a cutter-embedded structure, convenient and safe use is realized. Moreover, the cutter moves in the longitudinal direction by pressing of the support plate to guide a cutting action, thereby correctly cutting a Teflon-coated braid fishing line as well as a Nylon mono fishing line, providing excellent reliability in the cutting action, and providing durability to maintain excellent cutting force after long time use. Moreover, the portable fishing line cutter is floated on water, thereby preventing a loss caused by fall in water. Moreover, due to attachment by magnetic force, convenience in carriage is increased.본 발명은 일측면끼리 서로 마주보도록 위치하는 제 1 및 제 2 지지판； 상기 제 1 지지판에서 커터고정부에 의해 고정되어, 날이 상기 제 2 지지판을 향하도록 설치되는 커터； 및 상기 커터가 상기 제 2 지지판으로부터 이격되도록 상기 제 1 및 제 2 지지판을 서로 연결시키고, 상기 제 1 및 제 2 지지판이 서로 근접하도록 힘을 가하면, 상기 제 1 지지판이 상기 제 2 지지판으로부터 상기 커터의 길이방향으로 이동을 허용하도록 변형됨으로써, 상기 커터가 상기 제 2 지지판과의 사이에 개재되는 낚시줄을 커팅하도록 하며, 상기 힘을 해제시 상기 제 1 커터가 상기 제 2 지지판으로부터 이격되도록 상기 제 1 및 제 2 지지판를 복귀시키는 탄성연결부；를 포함하도록 한 휴대용 낚시줄 커터에 관한 것이다
