1. An optical connector ferrule comprising adhesive reservoirs having shapes of stepped grooves provided at corners in outer edges of an opening of an insertion opening portion having a shape of a rectangular opening of a main body of the ferrule, wherein the main body of the ferrule is formed by having: the insertion opening portion provided on a rear end side of the main body of the ferrule such that a boot having substantially a shape of a square tube and having an optical fiber core wire at a distal end is able to be inserted and supported in the insertion opening, and optical fiber core wire insertion holes provided on a front end side of the main body of the ferrule such that a side of a distal end portion of the optical fiber core wire is inserted into a deep portion of the insertion opening portion and the distal end portion is exposed outwardly, and an adhesive filling window formed on an upper surface of the main body of the ferrule to fix the optical fiber core wire from a side of the deep portion of the insertion opening portion to a side of each rear end opening of the optical fiber core wire insertion holes by filling an adhesive therein, wherein the adhesive reservoirs are formed to store an adhesive injected from the adhesive filling window and leaking out from a gap between the boot and the insertion opening portion.
