PURPOSE:To improve ozone removal performance without decreasing air permeability by providing plural elements of specific thickness which have ozone adsorption surfaces on their wall surfaces and many through holes in a passage direction in the internal passage of a cylinder body at specific intervals. CONSTITUTION:The elements 12a and 12b of specific thickness which have the ozone adsorption surfaces on their wall surfaces and many through holes 122a and 122b in the direction of the passage 111 are provided in the cylinder body 11 so that the passage 111 is closed. A turbulent flow generated at end parts of the through holes 122a and 122b stirs and mixes air in the space of an element nonarrangement part 134 to uniform the air which differs in ozone content. Consequently, the following element 12 adsorbs and removes ozone in an area which can not be removed by the leading element 12 to improve the ozone removal rate. |
