I investigate $^{10}$B+$alpha$ cluster states of $^{14}$N with a $^{10}$B+$alpha$ cluster model. Near the $alpha$-decay threshold energy, I obtain $K^pi=3^+$ and $K^pi=1^+$ rotational bands having $^{10}$B($3^+$)+$alpha$ and $^{10}$B($1^+$)+$alpha$ components, respectively. I assign the band-head state of the $K^pi=3^+$ band to the experimental $3^+$ at $E_x$=13.19 MeV of $^{14}$N observed in $alpha$ scattering reactions by $^{10}$B and show that the calculated $alpha$-decay width is consistent with the experimental data. I discuss an $alpha$-cluster motion around the $^{10}$B cluster and show that $^{10}$B+$alpha$ cluster states contain significant components of a linear-chain 3$alpha$ configuration, in which an $alpha$ cluster is localized in the longitudinal direction around the deformed $^{10}$B cluster.
