A lever switch device includes a shaft member, a rotary operation member, a push switch, and a flexible board. The flexible board has a first board part, a first wiring part connected to the first board part, a second board part, a second wiring part connected to the second board part, and an integrated wiring part. The first board part has a fixed contact. A movable contact of the rotary operation member comes into contact with and separates from the fixed contact in response to a positional shift of the rotary operation member. The second board part receives a signal output from the push switch. The integrated wiring part is at a position away from the first board part and the second board part, and a part of the first wiring part and a part of the second wiring part are integrated in the integrated wiring part.
