Provided are an air intake noise reducing device, an internal combustion engine having the air intake noise reducing device, and an installation structure for the air intake noise reducing device of the internal combustion engine. The air intake noise reducing device has a gasket (2) and a net member (3). The gasket (2) has a ring part (2a) held at a connection surface of an intake passage (100) and also has projection receiving parts (2b) extending from the ring part (2a) in the direction of the center of the intake passage. The net member (3) has a net part (3a) for straightening an intake air flow and also has connection projections (3b) extending from the net part (3a) to the outside of the intake passage. Connection projections (3b) are received in the projection receiving parts (2b) to secure the net member (3) to the gasket (2). Therefore, the man-hours for assembly are reduced, and the sealability of the intake passage is not impaired.
