We have measured the neutron electric form factor Gen via 3He→(e→,e′n)pp at Q2  =  0.67 (GeV/c)2 using the 3-spectrometer facility of the A1 Collaboration at the Mainz Microtron and a dedicated neutron detector. High pressure polarized 3He→ gas was used as a target of polarized neutrons. Gen is determined from the ratio of the asymmetries A⊥/A∥ measured in quasifree kinematics with the target spin perpendicular and parallel to the momentum transfer. We find Gen  =  0.052±0.011±0.005.
