PROBLEM TO BE SOLVED: To solve the problem that it is difficult that light-emitting regions are caused to emit light with high visibility in the case that a plurality of operation members sharing an irradiation part and having light-emitting regions respectively are three-dimensionally arranged.SOLUTION: An operation unit includes: an irradiation part; a first operation member including a first light guide path for guiding light of the irradiation part from a first end part to a first light emitting region forming at least a part of a second end part; and a second operation member including a second light guide path for guiding the light of the irradiation part, which has passed a part of the first light guide path, from a third end part adjacent to the first light guide path to a second light emitting region forming at least a part of a fourth end part. |
