Abstract
Ihara's proof that the reduction of the modular curve at a prime not dividing has many points over a quadratic extension is adapted to the drinfeld modular curves . In order to do so, some properties of drinfeld modular varieties that have no proof in the literature are proven. The text is more or less self-contained.
