An article storage rack is provided in which it is easy to form a downflow around an article being stored and which has shelf members each of which can properly support the weight of an article. An article storage facility that includes such an article storage rack is also provided. Each shelf member has a support plate portion which is generally plate-shaped and which extends along a horizontal plane, and support frame members which are located below the support plate portion to support the support plate portion from below, and is formed in a shape that tapers toward a distal end portion thereof such that the width of the support plate portion, along a rack lateral direction, is narrower toward the distal end portion. wherein each support frame member includes an elongate member located and arranged to extend along the support plate portion. And a pair of support frame members are provided to each shelf member such that one support frame member is located on each side of the support plate portion with respect to the cut-out portion, along the rack lateral direction. A proximal end side portion has a portion that overlaps with an article storing area formed under it as seen along the rack lateral direction. And both proximal end side portions of the pair of support frame members are located outside the article storing area along the rack lateral direction as seen along the vertical direction.
