Disclosed is a novolak resin containing a repeating unit represented by the general formula (1). R
1
is a hydrogen atom or an alkyl group which is C
1-4
straight-chain or C
3-4
branched-chain, and some or all hydrogen atoms in the alkyl group may be replaced with a fluorine atom; R
2
is a hydrogen atom, a phenyl group, an alkyl group which is C
1-10
straight-chain or C
3-10
branched-chain, or an alkyl group having a C
3-10
cyclic structure, and some or all hydrogen atoms in the phenyl group and the alkyl group may be replaced with fluorine atoms; each of a and b is independently an integer of 1-3, and these are defined as 2≦a+b≦4; and d is an integer of 0-2. This novolak resin has high dissolution rate in the alkaline development solution in addition to the heat resisting property which is a property of phenolic resin.
