Abstract: A liquid discharging apparatus includes: liquid discharging modules which are arranged in a first direction along a predetermined plane; and a wiring member commonly joined to the liquid discharging modules. The wiring member includes: first parts joined to the liquid discharging modules, respectively, in a state that the first parts are arranged side by side in the first direction along the predetermined plane; second parts; and a sixth part. The second parts include: third parts extending from the first parts, respectively, in a second direction orthogonal to the first direction and along the predetermined plane, fourth parts extending in a third direction away from the predetermined plane, and fifth parts connected to the third parts and the fourth parts, respectively. Width in the first direction of each of the second parts is smaller than width in the first direction of the sixth part.

Abstract: An actuator device includes: an actuator including piezoelectric elements arranged in a first direction and first contacts arranged in the first direction; a protector including a first wall opposed to the piezoelectric elements and a second wall coupled to the first wall and joined to a region of the actuator at which the first contacts are disposed; first connection terminals disposed on the first; and first through electrodes formed in the second wall to bring the first contacts and the first connection terminals into conduction with each other. A distance between two of the first through electrodes which respectively correspond to two of the piezoelectric elements which are adjacent to each other in the first direction is greater than a distance in the first direction between the two of the piezoelectric elements which are adjacent to each other in the first direction.

Abstract: An actuator device includes: an actuator including a first contact; and a wire member including a second contact connected to the first contact with a conductive adhesive including a conductive particle. One of the first contact and the second contact is a particular contact. The other of the first contact and the second contact is a specific contact. At least two protrusions and at least one recess are formed on and in the particular contact. The at least two protrusions are arranged in a first direction. The at least one recess is interposed between the at least two protrusions. The particular contact is joined to the specific contact with the conductive adhesive provided in the at least one recess, in a state in which each of the at least two protrusions is in contact with the specific contact.

Abstract: An actuator device includes: an actuator including a first element contact; and a wire member including (a) a first contact connected to the first element contact and (b) a first wire configured to conduct with the first contact. A first wide portion is formed at a distal end portion of the first wire at an edge portion of the wire member. The first wide portion is disposed beyond the first element contact in a wire direction of the first wire. The first contact is disposed at a basal end portion of the first wire. The basal end portion is located further from the edge portion of the wire member than the first wide portion. The first contact is connected to the first element contact.

Abstract: An actuator device includes: an actuator including first contacts arranged in a first direction; and a wire member including second contacts and joined to the actuator. The second contacts are arranged in the first direction and respectively connected to the first contacts. Each of particular contacts as the first contacts or the second contacts has a protruding and recessed portion including: at least two protrusions; and a recess between the at least two protrusions. The particular contacts include: at least one central-region contact disposed on a central region in the first direction; and at least one end-region contact disposed nearer to an end region than to the central region in the first direction.
