Stars are formed in cold and dense molecular clouds by gravitational
collapse. This big picture has well been drawn in the last few
decades. However, many details are little known. One of long-standing,
fundamental questions in star formation is what the roles of magnetic
fields are. Since several years ago theoretical and observational studies have
suggested that magnetic fields also significantly affect formation of
circumstellar disks at the earliest stages of young stellar objects.
The effects of magnetic fields on early disk formation will be discussed
with my recent ALMA observations toward the youngest protostellar
systems, which show the magnetic fields in small scales.
