In this paper, a study of light-cone distribution amplitudes (LCDAs) for p-wave heavy meson is presented in both general and heavy quark frameworks. Within the light-front approach, the leading twist LCDAs, \phi_M(u) and their relevant decay constants of heavy scalar, axial-vector and tensor mesons, f_M, are formulated. The relations of some decay constants can be simplified when the heavy quark limit is taken into account. After fixing the parameters that appear in a Gaussian wave function, the corresponding decay constants are calculated and compared with those of other theoretical approaches. The curves and the first six \xi-moments of \phi_M(u) are plotted and estimated. These results all endorse the requirements of heavy quark symmetry.
