Abstract
Diesel particulate filter that can lower the particulate matter (PM) combustion start temperature and use material containing silicon (Si) for a carrier. The carrier, which has a filter function, is allowed to support a perovskite-type complex oxide expressed by formula (1) as follows, wherein 0<x<0.7 and 0≦y≦1: formula (1)=La1-xBaxMnyFe1-yO3.
