Abstract: An optical ferrule and an optical connector are provided, which make it possible to reduce the labor required for an adhesive wiping operation even when the optical ferrule is small-sized. A first adhesive filling recess 113 is equipped, which is formed at an outlet of an optical fiber hole 112 so that a forward end of a bare fiber 120, which is positioned by the optical fiber hole 112, is allowed to abut against an inner wall 113w opposed to the outlet, and the bare fiber 120 is adhered and fixed in a resultant state by means of an adhesive 131 with which the recess is filled, wherein the first adhesive filling recess 113 is provided with adhesive accommodating recesses 115, 117 which are shallower than the first adhesive filling recess 113 and are disposed continuously with the first adhesive filling recess 113.

Abstract: A ferrule of the present invention includes a positioning mechanism for positioning an optical fiber, and a recess having at least a first inner wall for allowing a front end of the optical fiber portion positioned by the positioning mechanism to protrude, and a second inner wall opposite to the first inner wall. A distance between the first inner wall and the second inner wall is less than or equal to four times the outer diameter of the optical fiber. Adhesive is filled into the recess and cured in a state in which the optical fiber protrudes from the first inner wall and substantially contacts the second inner wall to fix the optical fiber.
