Abstract: Examples are introduced to show that subideals of Malcev algebras are different from their ideals. Some basic properties of Malcev algebras'subideals are given. Propositions are shown as follows: subideals of semisimple Malcev algebras are their ideals;idempotent subideals of a Malcev algebra are its ideals;subalgebras of a nilpotent Malcev algebra are its subideals;a Malcev algebra is solvable if its subalgebras are all subideals.

Key words: Malcev algebra, subideal, semisimple, solvable, nilpotent
