PURPOSE: To develop an inconspicuous temporary fixing member having no bad effect on an ornament, easy to handle, and never disturbing the admiration to prevent the loss of material property and a disaster by overturning and falling.

CONSTITUTION: This temporary fixing member 1 is formed of a viscous body having self-shape holding property easily deformable by fingers which mainly contains a mixture of a silicon bouncing patty single body consisting of boron-contained siloxane and silicon crude rubber, to which a reinforcing agent, a thickener, and a coloring agent are mixed as blending agents as occasion demands. The temporary fixing member 1 inconspicuously temporarily fixes a flower base 2 which is an objected to be fixed in the position of the bottom part making contact with a fixing surface 3. Only by adhering the temporary fixing member to the bottom part of the flower base 2 and placing it on the fixing surface 3, it is closely adhered thereto by dilatancy phenomenon and perfect plastic deformation, and a sucker effect is generated to allow the fixation. It can be easily separated from the flower base 2 or fixing surface 3 by viscous elongation in addition to non-coking property and non-transferring property.
