We report the discovery and the analysis of the planetary microlensing event,OGLE-2013-BLG-1761. There are some degenerate solutions in this event becausethe planetary anomaly is only sparsely sampled. But the detailed light curveanalysis ruled out all stellar binary models and shows that the lens to be aplanetary system. There is the so-called close/wide degeneracy in the solutionswith the planet/host mass ratio of $q \sim (7.5 \pm 1.5) \times 10^{-3}$ and $q\sim (9.3 \pm 2.9) \times 10^{-3}$ with the projected separation in Einsteinradius units of $s = 0.95$ (close) and $s = 1.19$ (wide), respectively. Themicrolens parallax effect is not detected but the finite source effect isdetected. Our Bayesian analysis indicates that the lens system is located at$D_{\rm L}=6.9_{-1.2}^{+1.0} \ {\rm kpc}$ away from us and the host star is anM/K-dwarf with the mass of $M_{\rm L}=0.33_{-0.18}^{+0.32} \ M_{\odot}$ orbitedby a super-Jupiter mass planet with the mass of $m_{\rm P}=2.8_{-1.5}^{+2.5} \M_{\rm Jup}$ at the projected separation of $a_{\perp}=1.8_{-0.5}^{+0.5} \ {\rmAU}$. The preference of the large lens distance in the Bayesian analysis is dueto the relatively large observed source star radius. The distance and otherphysical parameters can be constrained by the future high resolution imaging byground large telescopes or HST. If the estimated lens distance is correct, thisplanet provides another sample for testing the claimed deficit of planets inthe Galactic bulge.
