UEFA's Control, Ethics and Disciplinary Body announced the sanction which related specifically to crowd disturbances, the setting off of fireworks, and an illicit banner.
Sevilla, who won the match 3-1, were fined 17,000 euros for their part in the disturbances, which involved crowd disturbances and the throwing of objects.
A small numbers of supporters clashed behind one of the goals shortly before kick-off, with many fans blaming poor segregation for the problems.
There was also criticism of UEFA's choice of the St Jakob-Park stadium, which with its capacity of just 35,000 was the smallest chosen to host a major European final.
