An expansion anchor is provided having a stud and at least one expansion sleeve that surrounds the stud, whereby, on the stud, there is an expansion cone that radially widens the expansion sleeve when the expansion cone is pulled into the expansion sleeve. It is provided that the expansion sleeve has a hardness of more than 350 HV in the area of its front end facing the expansion cone, whereby the hardness of the expansion sleeve decreases towards its rear end. A production method for such an expansion anchor is also provided.
