We construct a realistic field-theoretic model for the structure of a heavy meson in the heavy quark limit. The model is fully covariant and satisfies heavy quark symmetry. The Isgur-Wise function, the decay constant, and the axial vector coupling constant are studied. This model overcomes the limitations caused by non-covariance of the light-front quark model, and provides an ideal framework to systematically evaluate the heavy quark symmetry breaking effects caused by the $1/m_Q$ correction terms in the heavy quark effective theory of quantum chromodynamics.
