A sound proof room (41a) has an interior space (43a) formed by sound proof walls (44a, 45a, 46a, 47a). The sound proof room (41a) contains a sound absorbing body (11a) with a sound absorbing face, which absorbs sound in the room, exposed to the interior of the room. The sound absorbing body (11a) has portions with differing thicknesses in the depth direction from a surface (19a), which is the sound absorbing face. The sound absorbing body (11a) is formed by layering a plurality of layering members in the depth direction from the surface (19a), which is the sound absorbing face.
