Sweden, which outshot the Finns 41-23 and capitalized on a pair of power plays, will play Team Canada in the championship on Sunday. The Canadians defeated Russia 4-2 earlier Saturday.
Sunday's gold medal game begins at 1:45 p.m. and will be broadcast on NHL Network.
Alexander Edler got the Swedes on the board less than two minutes into Saturday's game for a quick 1-0 advantage. Finland's Joonas Kemppainen knotted the contest less than three minutes later, and the teams were tied after 20 minutes.
Sweden blew the game open with two power-play goals in the second, getting tallies from defenseman John Klingberg and forward William Nylander. Joakim Nordstrom added a third-period goal to provide the final margin.
Nylander finished with a goal and an assist for the Swedes while Nicklas Backstrom had a pair of helpers.
Wild defenseman Jonas Brodin and forward Joel Eriksson Ek each played but did not figure into the scoring. Brodin received 16:49 of ice time while Eriksson Ek had three shots on goal and a penalty in 9:24.
