In the resin (P) of the present invention, the content of repeating units containing acid-decomposable groups (in› cluding the repeating unit (B2) and the repeating unit (C) to be described hereinafter), based on all the repeating units of the resin, is preferably in the range of 3 to 90 mo! %, more preferably 5 to 80 mo! % and most preferably 7 to 70 mo! %. 

The ratio between repeating unit (A) and repeating unit (B2) (number of moles of A/number of moles of B) in the resin is preferably in the range of0.04 to 1.0, more preferably 0.05 to 0.9 and most preferably 0.06 to 0.8. 

[Repeating Unit (C)] 

The resin (P) may further contain a repeating unit (C) that contains an acid-decomposable group but does not contain any aromatic ring group. 

The repeating unit (C) is preferably any of those of general formula (V’) below.

In general formula (V’), Rs$_{1 }$ to Rs$_{4 }$ are as defined above in connection with general formula (V). 

L’s, R’ss and R’s$_{6 }$ have the same meanings as those of Ls, Rss and Rs$_{6 }$ of general formula (V), respectively, except that L’s, R’ss and R’s$_{6 }$are neither aromatic ring groups nor groups having aromatic ring groups. 

Particular examples of the repeating units of general for› mula (V’) will be shown below, which however in no way limit the scope of the present invention.
