We study hadronic molecules formed by a heavy meson and a nucleon, DN and D*N (BN and B*N) systems. Respecting the heavy quark symmetry and chiral symmetry, we consider the DN\mathrm\text\ensuremath-D*N (BN\mathrm\text\ensuremath-B*N) mixing induced by the one boson exchange potential including the tensor force. We find many bound and resonant states with JP=1/2^\ifmmode±\else\textpm\fi, 3/2^\ifmmode±\else\textpm\fi, 5/2^\ifmmode±\else\textpm\fi, and 7/2^\ensuremath- in isospin singlet channels, while we find only a few resonant states with JP=1/2^\ensuremath- in isospin triplet channels. The analysis of DN and D*N (BN and B*N) molecules will be useful to study mass spectra of excited charmed (bottom) baryons with large angular momenta, when their masses are close to the DN and D*N (BN and B*N) thresholds.
