The Swedish team consists of Linn Grant, Maja Stark, Beatrice Wallin and captain Ingrid Lindblad.
The best of them on the first day was Lindblad, which is ranked second in the world among amateurs.
She played on 70 strokes, two under par.
Grant played one over par, Wallin three over par and Stark five over par.
The team's results are determined by the three best rounds in the team, so Stark's first round is excluded in Sweden's case.
Everyone except Wallin is among the ten best amateurs in the world and Wallin is in 18th place in the world rankings.
Switzerland leads after the first day, at three under par, and Sweden thus needs to play really well in the future to defend their European Championship gold.
