The present invention relates to a fluid sterilizer which installs a PCB having UV LEDs on both surfaces of the PCB in a pipeline in which a fluid flows to increase sterilization efficiency and minimize flow resistance of the fluid. The fluid sterilizer comprises: a body housing in which a fluid flows; an inner housing having a flow space formed in a flow direction of the fluid in the body housing; a circuit board accommodated in an accommodation space in the inner housing; and a plurality of UV LEDs mounted on both sides of the circuit board. The inner housing comprises a first surface and a second surface on both sides of the circuit board to face each other. The first surface and the second surface face each other around the circuit board. A portion of the UV LEDs are arranged on the first surface in the fluid flowing direction, and at least a portion of the remaining UV LEDs are arranged on the second surface in the fluid flowing direction. The fluid passes through the flow space facing any one surface of both surfaces of the circuit board to perform sterilization. |
