摘要：
To provide a sound absorbing structure having a superior sound absorbing characteristic and an external appearance of the sound absorbing structure which does not cause flicker or the like, by disposal, for example, in the front of an air chamber, a plurality of ribs (2a) are disposed on one surface of the sound absorbing board body (2), and a plurality of through-holes (3) are provided in basal portions (2b) between the ribs (2a) to form a porous structure. Concealing materials (5) are provided between the ribs (2a) of the sound absorbing board body to conceal the through-holes (3), respectively.
