At least the upper half of the whole of the outer circumference surface of a portion being in the tuyere trunk and projecting into the blast furnace, or the whole excluding the forefront of the outer circumference surface is coated with a shell layer 5 made of a material having a higher melting point than the melting point of Cu and temperature of a hot metal in the blast furnace. Furthermore, a jacket 4 made of a metal for protecting the tuyere from mechanical impacts received at the time of inserting the tuyere into the blast furnace is fitted onto the outside of the shell layer.
