A novel imidazole compound that yields a surface treatment liquid that is very effective at suppressing migration and oxidation of a wiring surface; a metal surface treatment liquid that contains the imidazole compound; a metal surface treatment method that uses the metal surface treatment liquid; and a laminate production method that uses the surface treatment liquid. A metal is surface-treated using the surface treatment liquid which includes a saturated fatty acid or a saturated fatty acid ester of a specific structure, in which a prescribed position is substituted by an aromatic group of a prescribed structure and an imidazolyl group that may have a substituent group.

Provided is a high-purity crystal of an unsaturated carboxylic acid amide compound which is useful as or for fine chemicals such as pharmaceuticals, agricultural chemicals, polymeric materials, functional materials, and intermediates of them. The crystal includes an unsaturated carboxylic acid amide compound represented by Formula (1) in an amount of 95 percent by area or more. In X-ray diffraction, the crystal exhibits peaks at 2&#x3b8; in the range of 29.0 to 30.0 and in at least one range selected from 6.0 to 8.0, 12.0 to 13.5, and 16.5 to 17.5 and exhibits approximately no peak at 2&#x3b8; in the range of 14.0 to 15.0.
