Rb$_{2 }$ and n$_{2 }$ in the formula have the same meaning as those in General  Formulas (LCl-1) to (LCl-17), respectively.  As the repeating unit including a sultone group which the  resin (A) has, a repeating unit formed by substituting the  lactone group in the repeating unit having an lactone group  described above with a sultone group is preferable.  The repeating unit ( c) may be a repeating unit having a  cyclic carbonic acid ester structure as a polar group.  The repeating unit having a cyclic carbonic acid ester  structure is preferably the repeating unit represented by the  following General Formula (A-1).  SLl-1  ~  0--S=O  II  0  SLl-2
