1. A method for manufacturing an insertion guide needle covering an outside of a body insertion section of a sensor unit to guide body insertion of the sensor unit for a continuous blood glucose monitoring device configured to be inserted into a body and measure blood glucose and being inserted into the body together with the sensor unit, the method comprising:
(a) preparing needle original plate of metal material lengthily formed along a direction of the body insertion;
(b) cutting a front end portion of the needle original plate to form an enlargement incision part configured to enlarge an incised portion of skin of the body as the insertion guide needle is being inserted into the body, wherein a front end portion of the enlargement incision part forms a dot point tip in a structure of point-contacting with the skin of the body; and
(c) bending both end side portions with respect to a width direction of the cut needle original plate after the step (b),
wherein the step (b) comprises:
first-cutting the needle original plate to form a first slanted surface in a direction of crossing with a length direction center axis passing an upper surface of the needle original plate; and
second-cutting the needle plate to form a second slanted surface in a direction of being symmetric to the first slanted surface with respect to the length direction center axis of the needle original plate,
wherein the first slanted surface and the second slanted surface are formed to be slanted in a direction of being away from a virtual plate comprising the length direction center axis of the needle original plate and the dot point tip as being toward a bottom of the needle original plate.
