The sound absorbing board includes a body (10) and multiple sound absorbing elements (20). The body (10) has a first side surface (11) and a second side surface (12). The multiple sound absorbing elements (20) are formed on the body (10) at spaced intervals, and each one of the multiple sound absorbing (20) elements has a protrusion (21), a groove (22), and two sound absorbing openings (23). The protrusion (21) is formed on the first side surface (11) of the body (10). The groove (22) is formed on the second side surface (12) of the body (10) and has multiple concave portions (221) and at least one convex portion (222). The multiple concave portions (221) are formed on a bottom surface of the groove (22). The at least one convex portion (222) is formed on the bottom surface of the groove (22), and is formed between two adjacent ones of the multiple concave portions (221). The two sound absorbing openings (23) are formed on the two opposite side surfaces of the protrusion (21), respectively. 211 Di
