PROBLEM TO BE SOLVED: To provide a boring jig which has a high mechanical strength and a high durability, and can position the boring position and can guide the boring, rapidly, at a high accuracy, and in a good workablilty, when numerous holes are bored at a desired pitch, and even when the hole pitch of the work is different from the hole pitch of a guide hole. SOLUTION: This boring jig is provided with an upper jig main body 3 arranged opposing to the boring surface of a work 2, and plural guide holes 6 where a drill is inserted at a specified pitch in an X-axial direction to the boring surface are formed; a rod 10b arranged at one end in the X-axial direction of the upper jig main body 3, and to regulate the position in the X-axial direction in the boring surface of the work 2; a lower jig main body 4 arranged orthogonal to the rod 10b, abutting to the other side standard end face of the work 2, and to regulate the position in the Y-axial direction at the boring surface of the work 2; and a micrometer 10 which can regulate minutely the boring position of the work 2 within the hole pitch, in order to fit to the nearest guide hole 6.
