Abstract: In a blower fan according to a preferred embodiment of the present invention, a side wall portion includes a tongue portion arranged to project between an air outlet and an impeller. A side surface of the tongue portion includes a tongue portion tip arranged to touch a first imaginary plane including a central axis; a first tongue portion side surface arranged to extend from the tongue portion tip along an outer envelope of the impeller; and a second tongue portion side surface arranged to extend from the tongue portion tip toward a side edge, the side edge being a line of intersection of the air outlet and the side wall portion. The second tongue portion side surface is arranged to cross a second imaginary plane including the central axis and touching the side edge.

Abstract: A lower plate includes a lower air inlet arranged radially outward of a bearing portion. In a plan view, a plane is divided into four regions by a first straight line which is parallel to an air outlet and crosses a central axis and a second straight line which is perpendicular to the air outlet and crosses the central axis, and one of the four regions in which a tongue portion is arranged is a first region, followed by a second region, a third region, and a fourth region in this order in a rotation direction of the blades. The air outlet is arranged to extend over both the first and fourth regions.
