When the  The structural unit (a3) of the component (Al) may be  either a single type of structural unit or a combination of two  or more types of structural units.  In formula (a3-10), w" is preferably 1 or 2, and more  preferably 1.  In formula (a3-9), v" is preferably 1 or 2, and more pref- erably 1.  In formula (a3-8), r" is preferably 1 or 2, and more prefer› ably 1.  In formula (a3-4), q is preferably 1 or 2, and more prefer› ably 1. When q is 2, it is preferable that the cyano groups are  bonded to the 3rd and 5th positions of the adamantyl group.  When q is 1, it is preferable that the cyano group is bonded to  the 3rd position of the adamantyl group.  In formula (a3-3), t’ is preferably  1. I is preferably 1. sis  preferably 1. Further, it is preferable that a 2-norbornyl group  or 3-norborny I group is bonded to the terminal of the carboxy I  group of the acrylic acid. The fluorinated alkyl alcohol is  preferably bonded to the 5th or 6th position of the norbornyl  group.  In formula (a3-2), k is preferably  1. The cyano group is  preferably bonded to the 5th or 6th position of the norbornyl  group.  When j is 2, it is preferable that the hydroxyl groups are  bonded to the 3rd and 5th positions of the adamantyl group.  In formula (a3-l), j is preferably 1 or 2, and more prefer- ably 1. Whenj is 1, it is preferable that the hydroxyl group is  bonded to the 3rd position of the adamantyl group.  In the above formulas, R is the same as defined above, j  represents an integer of 1 to 3, k represents an integer of 1 to  3, t’ represents an integer of 1 to 3, I represents an integer of 1  to 5, s represents an integer of 1 to 3 and each of q, r", v" and  w" independently represents an integer of 1 to 3.
