An air cleaner has a filter, an annular filter holder formed on the peripheral edge of the filter, a flange portion of U-like cross-section to which the outer circumference of the filter holder is embedded, and a case provided with an air inlet port and an air outlet port. This case is molded in blow molding using a filter member constituted integrally by the filter and the filter holder as an insert. In this air cleaner, the constitution parts, become as little as possible.
