PURPOSE: To effectively increase the concentration magnification of an air component concentrating device. CONSTITUTION: This air component concentrating device is provided with dividing means 15, 18 and 20 that an adsorbing stage for adsorbing the component to be concentrated in the gas Ai to be treated to an adsorbent layer 4 and a desorbing stage for desorbing the component to be concentrated adsorbed to the adsorbent layer 4 in the gas Hi for desorbing are repeated, and the desorbing gas Ho sent from the adsorbent layer 4 containing the desorbed component to be concentrated at the desorbing stage is divided into the first stage passed gas Hof passed the adsorbent layer 4 at the first stage of the desorbing stage and the latter stage passed gas Hor passed the adsorbent layer 4 at the latter stage of the desorbing stage, and the first stage passed gas Hof is passed through again the adsorbent layer 4 at the repeating adsorbing stage in the state as a part of the gas Ai to be treated and the other side latter stage passed gas Hor is taken out as formed concentrated gas.
