  We construct a natural inflation model with the inflaton as a linear
combination of the fifth components of Abelian gauge fields in a
five-dimensional theory. A seesaw mechanism is introduced to provide a natural
milli-charge for matter fields under one combination of the gauge symmetries.
As a result, the effective decay constant of the inflaton field can be above
the Planck scale with all scales in the model below the Planck scale. Our model
predicts a tensor-to-scalar ratio r between 0.033 and 0.125 for sixty e-folds
and a reheating temperature of a few 10^11 GeV.
