A sound absorbing structure (1) includes: a rear surface member (21) having a length in a predetermined direction; a front surface member (22) that is shorter in the predetermined direction than the rear surface member (21); and a sound absorbing material (3) that is placed in front of the rear surface member (21). The front surface member (22) is parallel to the rear surface member (21) and is separated forward from the rear surface member (21). An opening (23) is formed at a position adjoining the front surface member (22) in the predetermined direction. The sound absorbing material (3) is provided in both a first region (24) located behind the opening (23) and a second region (25) sandwiched between the front surface member (22) and the rear surface member (21).
