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.
