A search is performed for W H production with a light Higgs boson decaying to hidden-sectorparticles resulting in clusters of collimated electrons, known as electron-jets. The search is performedwith 2.04 fb−1 of data collected in 2011 with the ATLAS detector at the LHC in proton?proton collisions√at s = 7 TeV. One event satisfying the signal selection criteria is observed, which is consistent withthe expected background rate. Limits on the product of the W H production cross section and thebranching ratio of a Higgs boson decaying to prompt electron-jets are calculated as a function of aHiggs boson mass in the range from 100 GeV to 140 GeV.
