  We study anisotropic inflation in the Brans-Dicke gravity in the presence of
an abelian gauge field where the gauge field is non-minimally coupled to the
inflaton. We show that the degree of anisotropy, under slow-roll
approximations, is proportional to slow roll parameter of the theory. As
demonstration, we consider the displaced quadratic potential for the inflation.
We do the numerical calculation of the model to investigate the behavior of
anisotropy by changing the parameter in the Brans-Dicke model. We find out
that, the solution is an attractor in the phase space, and anisotropy grows
with number of e-folds. Anisotropy depends on Brans-Dicke parameter, $ \omega
$, initial values of the scalar field and constant parameter of the coupling
function of the scalar field and the abelian gauge field, $ c $. If we consider
upper bound on the number of e-folds from CMB i.e. $ 60 $ e-folds, by
increasing $ \omega $ and $ c $, anisotropy do not have time to exit the
horizon and suppressed.
