Abstract

A liquid jetting apparatus includes: a head unit including a first driving element, a second driving element, a first contact portion connected to the first driving element, and a second contact portion connected to the second driving element; and a wiring member including a flexible substrate, a first driving IC provided on the flexible substrate, a second driving IC provided on the flexible substrate, a first wire formed in the flexible substrate and connecting the first driving IC and the first contact portion, and a second wire formed in the flexible substrate and connecting the second driving IC and the second contact portion. A conductive part different from the first wire and the second wire is disposed in an area of the flexible substrate between the first driving IC and the second driving IC.
