## Abstract

A limit on the electron-neutrino charge radius |r| is derived from a measurement of the weak-neutral-current vector coupling constant gV obtained in electron-neutrino electron elastic scattering. The 90%-confidence interval for gV is -0.177<gV<0.187, which for sin2W=0.227 implies that the e mean-square charge radius is in the range -2.74×10-32<r2<4.88×10-32 cm2, or simply |r|<2.2×10-16 cm. This is the first experimental bound on the e charge radius, and is the same order of magnitude as bounds for structure.
