An objective of the present invention is to provide an air compressor in which internal heat exchange efficiency is increased and space utilization of a cooling unit is increased. According to an aspect of the present invention, an air compressor comprises: a housing; a rotation shaft disposed inside the housing; a compression unit connected to the rotation shaft to compress and discharge inlet air; a motor unit driving the rotation shaft; a control board for controlling the motor unit; and a filter unit for filtering noise of external power and supplying the same to the control board. The housing includes a first cooling passage for cooling the motor unit and a second cooling passage for cooling the filter unit, wherein the first cooling passage and the second cooling passage communicate with each other. 본 발명의 일 측면에 따른 공기 압축기는 하우징, 상기 하우징 내부에 배치되는 회전축, 상기 회전축과 연결되어 유입 공기를 압축하여 토출하는 압축부, 상기 회전축을 구동하는 모터부, 상기 모터부를 제어하는 제어기판 및 외부 전력의 노이즈를 필터링하여 상기 제어기판에 공급하는 필터부를 포함하고, 상기 하우징은 상기 모터부를 냉각하기 위한 제1 냉각유로와 상기 필터부를 냉각하기 위한 제2 냉각유로를 구비하되, 상기 제1 냉각유로와 상기 제2 냉각유로는 연통되는 것을 특징으로 할 수 있다.
