However, in such an air cleaner for an internal combustion engine, an adsorption sheet having a filter portion for adsorbing HC (hydrocarbon) is inserted into a resin frame. As a result, in the process of cooling the product (adsorption sheet) after insert molding, the resin frame forming the outer peripheral portion of the adsorption sheet contracts, and distortion occurs in the adsorption filter surrounded by this resin frame. Therefore, this distortion causes turbulence in the air flow passing through the filter portion of the suction sheet, which adversely affects the measurement accuracy of the air flow rate measurement sensor (air flow meter) arranged on the downstream side of the suction sheet.
