  In order to investigate the composite gauge field, we consider the
compositeness condition (i.e. renormalization constant $Z_3=0$) in the general
non-abelian gauge field theory. We calculate $Z_3$ at the next-to-leading order
in $1/N_f$ expansion ($N_f$ is the number of fermion flavors), and obtain the
expression to the gauge coupling constant through the compositeness condition.
Then the gauge coupling constant is proportional to $1/\sqrt{4N_f
T(R)-11C_2(G)}$ where T(R) is the index for a representation R of gauge group
G, and $C_2(G)$ is the quadratic Casimir. It is found that the gauge boson
compositeness take place only when $N_f T(R)/C_2(G) > 11/4$, in which the
asymptotic freedom in the non-abelian gauge field theory fails.
