1. An elastic fiber treatment agent comprising a smoothing agent and an alkyl phosphate ester compound, wherein
the alkyl phosphate ester compound contains a phosphate ester Q1 represented by the following formula (1) and at least one or more selected from the group consisting of a phosphate ester Q2 represented by the following formula (2) and a phosphate ester Q3 represented by the following formula (3),
at least one of M1 to M4 in the following formulas (1) to (3) is an alkaline earth metal, and
in a P nucleus NMR measurement of the alkyl phosphate ester compound upon an alkali over-neutralization pretreatment, a P nucleus NMR integral ratio attributed to the phosphate ester Q1 is 15% to 60% if the sum of P nucleus NMR integral ratios attributed to the phosphate ester Q1, the phosphate ester Q2, the phosphate ester Q3, and phosphoric acid and its salt is taken as 100%,
