PROBLEM TO BE SOLVED: To firmly fix indications on the surface of a silicone hose. SOLUTION: An ink 2 made from a silicone rubber based material and colors is printed on a surface 1 of the hose. Upon forming an indication portion 3 with thermo-bridge-building, silicone rubber on the surface 1 of the hose and the silicone rubber based material in the ink 2 are combined with bridge-building connection. Consequently, the ink 2 is not easily removed even though the indication portion 3 is rubbed, and the ink 2 does not elute so that the ink withstands alcohol, and oils and fats.
