The invention provides a centrifugal blower with high air blowing efficiency. An internal space (A1, A2) of a scroll housing (40) is divided by a dividing wall portion (43b) into a one side space (A1) and an other side space (A2). A boundary between a peripheral face portion (43a) and the dividing wall portion (43b) is formed of a one side boundary portion (44) formed in such a way as to face the one side space and an other side boundary portion (45) formed in such a way as to face the other side space (A2). At least one of the one side boundary portion (44) or the other side boundary portion (45) is formed in a curved form in a circumferential direction of a rotary shaft (32a).
