Abstract
We present new measurements of the He abundance of the Galactic bulge based on IR photometry of several bulge fields. The fields cover a wide range of distances from the Galactic center, allowing to study possible effects of disk contamination and the He gradient in the bulge. The findings are: 1) the mean He abundance of the Galactic bulge is Y = 0.28 ± 0.02, and 2) there is no significant He gradient in the bulge.
