This outdoor unit is provided with: a housing; an axial flow blower that forms, by rotary blades, a flow of air passing through the housing; and a heat exchanger that has a plurality of flat pipes arranged in the vertical direction with gaps therebetween, that is disposed in the radial direction with respect to the rotation axis of the axial flow blower, and that is disposed on the windward side of the axial flow blower in the flow of air formed by the axial flow blower. The plurality of flat pipes each have a flat shape having a long axis passing a first end portion located on the disposition side of the axial flow blower and a second end portion located, relative to the first end portion, on the windward side of the flow of air passing through the heat exchanger. When a first vector represents a vector that is in the rotation direction of each of the rotary blades and that is a tangent line of an opposing part, in a rotation circle drawn by the leading end of the rotary blade, at a position closest to the heat exchanger, and a second vector represents a vector that passes the first end portion of a first flat pipe disposed at the position closest to the opposing part among the plurality of flat pipes from the second end portion as a starting point, an angle formed by the first vector and the second vector is less than 90 degrees.
