An intake noise reduction device (100) disposed on a downstream side of a throttle valve in an intake pipe and including a flow-guiding net (110) that guides an air flow, wherein the flow-guiding net includes a mesh that is configured to be fine in a vicinity of a center of a flow passage in the intake pipe and to become coarser with distance from the vicinity of the center. For example, the mesh flow-guiding net (110) is formed of a plurality of radial portions (111) extending radially outward from the vicinity of the center of the flow passage in the intake pipe and a plurality of concentric portions (112) provided concentrically from the vicinity of the center.",
