Claim 9:
10. A production method for the silicon-containing polymer according to claim 1, the production method comprising:
performing an ene-thiol reaction between a carboxylic acid derivative and a precursor polymer including poly-silane chain or oligo-silane chain in a molecular chain and including an unsaturated hydrocarbon group represented by a following formula (2-I) bound onto a silicon atom:

—R4—CR5═CH2  (2-I)

wherein, in the formula (2-I), R4 is a single bond or a hydrocarbon group having 1 or more and 8 or less carbon atoms, R5 is a hydrogen atom or a hydrocarbon group having 1 or more and 8 or less carbon atoms, and in cases where both R4 and R5 are hydrocarbon groups, a sum of the number of carbon atoms in the hydrocarbon group as R4 and the number of carbon atoms in the hydrocarbon group as R5 is 2 or more and 8 or less,
wherein, the carboxylic acid derivative is represented by a following formula (1-I):

HS—R2—(CO—O—R3)n  (1-I)

wherein, in the formula (1-I), R2, R3, and n are the same as the R2, R3, and n in the formula (1),
or
performing an ene-thiol reaction between an unsaturated group-containing compound and a precursor polymer including poly-silane chain or oligo-silane chain in a molecular chain and including a mercapto group-containing group represented by a following formula (2-II) bound onto a silicon atom:

—R1—SH  (2-II)

wherein, in the formula (2-II), R1 is the same as the R1 in the formula (1),
wherein, the unsaturated group-containing compound is represented by a following formula (1-II):

CH2—CR7—R6—(CO—O—R3)n  (1-II)

wherein, in the formula (1-II) R3 and n are the same as the R3 and n in the formula (1), R6 is a single bond or a hydrocarbon group having 1 or more and 8 or less carbon atoms, R7 is a hydrogen atom or a hydrocarbon group having 1 or more and 8 or less carbon atoms, and in cases where both R6 and R7 are hydrocarbon groups, a sum of the number of carbon atoms in the hydrocarbon group as R6 and the number of carbon atoms in the hydrocarbon group as R7 is 2 or more and 8 or less.
