A centrifugal air blower includes a fan; and a scroll casing. The scroll casing includes: a sidewall covering the fan from an axial direction of a rotation axis, the sidewall having a suction opening for sucking air; a discharge opening; a tongue portion for guiding the airflow to the discharge opening; a peripheral wall surrounding the fan from a radial direction of the rotation axis; and a bell mouth formed along the suction opening of the sidewall. The bell mouth includes upstream and downstream ends, with the upstream end being an end portion on an upstream side in a direction of flow of the air passing through the suction opening, and the downstream end being an end portion on a downstream side in the direction of flow of the air.
