Claim 0:
1. A chemical liquid comprising:
water;
a hydroxylamine compound selected from the group consisting of hydroxylamine and a hydroxylamine salt, and
two or more kinds of specific compounds represented by Formula (1),, in Formula (1), R1 to R3 each independently represent a hydrogen atom or a substituent,
one or two R1, R2, or R3 represents a specific substituent containing —CO—NH—, wherein the —CO— of the —CO—NH— is a carbonyl group,
R1 and R2 may be bonded to each other to form an aromatic ring which may have a substituent, and
in a case where R1 and R2 are bonded to each other to form an aromatic ring which may have a substituent, R3 represents the specific substituent,
in a case where R1 and R2 are not bonded to each other to form an aromatic ring which may have a substituent, one or two of R1 to R3 represent a group represented by Formula (2),

-L2-COOH  (2)

in Formula (2), L2 represents a single bond or a divalent linking group that does not contain —CO—NH—,
wherein the chemical liquid comprises both the hydroxylamine compound and the specific compounds of Formula (1), and
a mass ratio of a content of a specific compound which takes up the highest proportion of the specific compounds to a content of a specific compound which takes up the second highest proportion of the specific compounds is 500 or less.
