The man, who is in his 20s, is also sentenced to pay just over 1.2 million kronor in damages to the victim, a related girl.
The crimes are said to have been committed between 2023 and 2026. The man has also worked in Falu municipality's school operations, but there is no connection between his job and the crimes. He denies any wrongdoing.
The man has been in custody since last spring.
