A Visa is required, unless you qualify to transit without a visa:
Passengers transiting through Stockholm (ARN) and arriving from a non-Schengen Member State with a confirmed onward ticket for a flight on the same calendar day to a third country which is not a Schengen Member State. They must: - stay in the international transit area of the airport, and - have documents required for the next destination.
