We demonstrate a p-wave optical Feshbach resonance (OFR) using purely long-range molecular states of a fermionic isotope of ytterbium 171Yb, following the proposition made by K. Goyal et al. [Phys. Rev. A 82, 062704 (2010)]. The p-wave OFR is clearly observed as a modification of a photoassociation rate for atomic ensembles at about 5 micro Kelvin. A scattering phase shift variation of \delta\eta = 0.023 rad is observed with an atom loss rate coefficient K = 7.5*10^{-12} cm^3/s.
