To provide an atmospheric pollutant removing type sound insulating wall by which noise prevention efficiency is dramatically improved compared to a conventional sound insulating wall, and an atmospheric pollution preventing function can be obtained.

The atmospheric pollutant removing type sound insulating wall comprises an exterior wall, an interior wall, an inner space formed between them, and openings for communicating an inner space with the outside. A sound absorbing material is arranged in each of the exterior wall and the interior wall. The inner space forms a passage allowing an air current to pass inside the wall from the lower end to the upper end. The passage communicates with the sound absorbing material arranged in each of the exterior wall and the interior wall. The openings include a lower end opening formed at the lower end of the wall to take the air current generated on the road surface upon the travelling of a vehicle into the inner space, and an upper end opening formed at the upper end of the wall to discharge the air current going up through the inner space to the outside. The lower end opening is opened toward the road on which the vehicle travels, and along the road surface. The opening of the inner space forming an air current passage is narrowed to form an air current curtain to block noise wave diffraction at the upper end opening.
