We report on the results of ∼7.5 yr of the very high energy (10-600 GeV) observations of HESS J0632+057 with Fermi-Large Area Telescope. In the highest energy band, 200-600 GeV, the source is detected with the statistical significance >=4.7σ at orbital phases 0.2-0.4 and 0.6-0.8 at which HESS J0632+057 is known to demonstrate enhanced emission in TeV energy band. The analysis did not reveal the emission from HESS J0632+057 at lower energies and different orbital phases. Using the upper limits on source's flux, we locate the break of the spectrum to >140 GeV and low-energy slope <1.6 (3σ statistical significance).
