"It is about your future, the future of your children and the future of your parents," she said, praising Laschet as a "bridge-builder who will get people on board" in shaping Germany, AFP reported.
Laschet, 60, has been trailing his Social Democrat challenger Olaf Scholz in the race for the chancellery, although final polls put the gap between them within the margin of error, making the vote one of the most unpredictable in recent years.
Merkel had planned to keep a low profile in the election battle as she prepares to bow out of politics after 16 years in power. But she has found herself dragged into the frantic campaign schedule of the unpopular chairman of her party, Laschet.
In the last week of the campaign, Merkel took Laschet to her constituency by the Baltic coast and on Friday headlined the closing rally gathering the conservatives' bigwigs in Munich.
Merkel tugged at the heartstrings of Germany's predominantly older electorate on Friday, calling them to keep her conservatives in power for the sake of stability — a trademark of Germany.
"To keep Germany stable, Armin Laschet must become chancellor, and the CDU and CSU must be the strongest force," she said.
At the other end of the country, Scholz held "dialogues on the future" with voters in his constituency of Potsdam — a city on the outskirts of Berlin famous for its palaces that once housed Prussian kings.
Scholz, currently finance minister from Merkel's junior coalition partners SPD, has avoided making mistakes on the campaign trail, and largely won backing as he sold himself as the "continuity candidate" after Merkel in place of Laschet.
Also on the campaign trail on Friday, Scholz demanded a "fresh start for Germany" and "a change of government" after years under Merkel.
Described as capable but boring, Scholz has consistently beat Laschet by wide margins when it comes to popularity.
