To provide a new substituted aminoaryladamantane derivative capable of being simply produced from an easily available compound and capable of being easily induced into an aminoaryladamantane derivative useful as a raw material, etc., for a highly functional material.

This substituted aminoaryladamantane derivative is expressed by formula (1) [R1, R2, R3, R4, R5 and R6 are identical to or different from one another and are each hydrogen, an aromatic cyclic group expressed by formula (2) (Z is an aromatic ring, R7 is a hydrolyzable protecting group, R8 is hydrogen, a hydrocarbon group or a hydrolyzable protecting group, and p is an integer of not less than 1, provided that two or more R7's and R8's are identical to or different from one another, when p is two or more, and the aromatic ring may have a substituent other than a substituent specified in the above) or a substituent other than the group expressed by formula (2), provided that at least one of R1, R2, R3, R4, R5 and R6 is a group expressed by formula (2)] or the like.
