Abstract: The present invention is to provide a flexographic printing plate having high ink transferability and making it possible to perform printing with a high ink density in a solid portion, a flexographic printing plate precursor, a method for manufacturing a flexographic printing plate, and a method for manufacturing a flexographic printing plate precursor. A flexographic printing plate of the present invention includes a relief layer including a non-image area and an image area having an uneven structure formed on a surface, in which the uneven structure is composed of recessed portions consisting of a plurality of grooves and projecting portions other than recessed portions, each of the plurality of grooves has a length of at least 30 μm, all of the plurality of grooves are grooves having a line edge roughness in a range of 0.5 to 2.5 μm in a region of 30 μm of the groove in a longitudinal direction, a depth of the recessed portion is 5 to 25 μm, and a ratio of the projecting portion is 5% to 60% of a geometric area of the uneven structure.
