A search for pair production of first-generation scalar leptoquarks in a final state containing an electron, a neutrino, and at least two jets is performed using proton-proton collision data at √s=7 TeV. The data corresponding to an integrated luminosity of 36 pb-1 were collected by the CMS detector at the CERN LHC. The number of observed events is in good agreement with the predicted yield for Standard Model processes. Prior results from CMS in the dielectron channel are combined with this electron+neutrino search. A combined 95%-confidence-level lower limit of

339 GeV is set on the mass of a first-generation scalar leptoquark for β of 0.5, where β is the

branching ratio for the leptoquark to decay to an electron and a quark. These results represent the most stringent direct limits to date for values of β greater than 0.35.
