Bernard joined PSG in 1977 but after Dominique Baratelli joined, he left the club a year later and moved to Brest (1978-84) and then to Monaco (1984-85).
At the end of his career, he set up home in the Finistere, where he died.
"Paris Saint-Germain present their condolences to his family and those close to him," PSG said in a statement.
