Abstract: A fan includes an inlet part disposed to form a fan inlet, a base disposed to form, together with the inlet part, a fan outlet, and a blade. The blade extends from the base to the inlet part, and includes a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base, and a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part.
