Abstract Multi-electron production has been measured at high transverse momentum in 115 pb-1} of positron- and electron-proton collisions collected by the H1 experiment at HERA. Good overall agreement is found with the Standard Model predictions, dominated by photon-photon interactions. Six events are observed with a di-electron mass above 100 GeV, a domain where the Standard Model prediction is low.
