I will explain the proof of an integral period relation for the quadratic base change of an elliptic modular form $f$  and the application to the proof of a conjecture of Hida on the congruence number measuring the congruences between the base change of f and forms which are not coming from $\Q$. This is joint work with J. Tilouine
