How to say "legislator" in Japanese

• 立法者りっぽうしゃ
  nounThe general word for a legislator: a person who makes laws. It suits discussion of lawmaking itself, including members of a legislature, though it is a less common word.
  その州しゅうの立法りっぽう者しゃは時代遅じだいおくれの法律ほうりつを廃止はいしした。↗

  The legislators of that state did away with outdated laws.
• 議士ぎし
  nounDenotes a member of a council or assembly — a councillor — and, as 'legislator', a member of a legislature; typical of political reporting, it stresses the seat held rather than lawmaking, and is less common.

Use 立法者 for a legislator in the general sense of someone who makes laws; 議士 denotes a member of a council or assembly, so it fits a councillor or member of a legislature rather than the abstract law-maker.
