In the composition of a Ag alloy type material used for production of flutes, a specified amount of at least one of Ni, Fe, Co and Cr or at least one of Mn, Ti, Zi and Si is added to suppress softening and crystal grain size coarsening caused by annealing in production. Thus, flutes which generate brilliant sounds in mid to high notes can be obtained by using the above material.
