A liquid-ejecting device includes a feed roller that conveys a medium, an ejection head that ejects a liquid while reciprocating along the medium, a rotational position detector including a rotational position detection scale to detect a rotational position of the feed roller, and a movement position detector including a movement position detection scale to detect a movement position of the ejection head. The rotational position detection scale and/or the movement position detection scale is subjected to a surface treatment that adapts at least one surface thereof to the liquid.
