<P>PROBLEM TO BE SOLVED: To provide a simple means capable of easily applying a colloidal solution of a noble metal or copper. <P>SOLUTION: The colloidal solution is obtained by reducing a noble metal compound or copper compound to the noble metal or copper, after dissolving the noble metal compound or copper compound in a solvent to add a high molecular weight pigment dispersant to the dissolved noble metal compound or copper compound. Then, the colloidal solution contains noble metal or copper colloidal particles having the particle diameter of several nanometer to several ten nanometer, with high concentration. A pen type applicator is provided with: a cylindrical body 1 having one end opening closed; a synthetic fiber made inner cotton body 2 impregnated with a colloidal solution diluted with a volatile solvent and housed in the body; a cylindrical fixed member 3 fitted into another end opening of the body and projected to be tapered toward the tip; a pen point 4 inserted into the tip of the fixed member and projected from the tip of the fixed member; a relay core 5 inserted into the inside of the fixed member, having an one end side joined to the pen point, having another end side projected into the inside of the synthetic fiber made inner cotton body and supplying the colloidal solution to the pen point from the synthetic fiber made inner cotton body; and a cap 6 detachably attached to another end of the body and covering the pen point. <P>COPYRIGHT: (C)2012,JPO&INPIT |
