<P>PROBLEM TO BE SOLVED: To solve problems of a conventional carbohydrate microneedle wherein the needle part is broken in a part around a weak bonded part between the needle part and a base plate part and the needle part cannot stick in the skin when the needle part is inserted into the skin because the needle part and the base plate part are made of different materials and the bond between the needle part and the base plate part is weak, and wherein the practical utility is extremely impaired because a medicament, etc. is mounted on the upper surface of the needle part only, and as a result, the size of the medicament etc. is limited and the dose of the medicament to the skin is limited, or the like. <P>SOLUTION: The carbohydrate microneedle is composed of one or a plurality of carbohydrate microneedles disposed and integrated in the shape of a comb on a side face of a microneedle attaching margin. The attaching margin is welded to a side end or biting part on the upper surface of the base plate made of a different material. As a result, the strength in the vicinity of the root of the needle part is high, so that the effect of easy sticking in the skin, and the effect of mounting a larger quantity of medicaments on the upper surface of the needle part and the upper surface of the attaching margin can be provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
