The invention discloses a flexographic printing plate, an original plate of a flexographic printing plate, a manufacturing method of a flexographic printing plate and a manufacturing method of an original plate of a flexographic printing plate. The present invention addresses the problem of providing a flexographic printing plate that has high ink transferability at a solid part and allows printing at high ink concentration, an original plate of the flexographic printing plate, a method for manufacturing the flexographic printing plate, and a method for manufacturing the original plate of theflexographic printing plate. The flexographic printing plate according to the present invention has a relief layer provided with a non-image part and an image part having a concavo-convex structure ona front surface thereof, wherein the concavo-convex structure is constituted by concave parts of a plurality of grooves and convex parts other than the concave parts, each of the plurality of grooveshas a length of at least 30 [mu]m, each of the plurality of grooves has a line edge roughness of 0.5 to 2.5[mu]m in a 30 [mu]m region in a longitudinal direction of the grooves, the concave parts have a depth of 5 to 25[mu]m, and the convex parts account for 5 to 60 % of a geometrical area of the concavo-convex structure.
