The present invention relates to a passive air sampler characterized by comprising; a case with open one side and the other side having a hole; a cover positioned in separation from one side of the case; a connecting member connecting the case and the cover; and a polyurethane filter and a glass fiber filter inside the case to filter the air flowing into the case through the space between the case and the cover. The passive air sampler according to the present invention can simultaneously collect residual organic contaminants or semi-volatile organic compounds formed in a gas phase/ particulate phase, and air can flow into the inside of the case more efficiently so as to be used usefully since the case of the sampler is shaken by wind.
