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.

First claim

What is claimed is:

1. A method of manufacturing an actuator device, comprising:
forming a wire pattern including a plurality of wires and a plurality of test contacts on a base of a wire member, the plurality of test contacts being respectively connected to the plurality of wires;
performing a conduction test of each of the plurality of wires using a corresponding one of the plurality of test contacts;
cutting the base along an area between the plurality of wires and the plurality of test contacts after the conduction test; and
joining the wire member to an actuator in a state in which a portion of each of the plurality of wires which is further from a cut edge of the base than a wide portion formed by the cutting of the base overlaps a corresponding one of a plurality of element contacts of the actuator.

2. The method of manufacturing the actuator device according to claim 1 , further comprising covering the base of the wire member with an insulating layer except a particular wire portion and the plurality of test contacts, the particular wire portion being the portion of each of the plurality of wires which is further from the cut edge of the base than the wide portion.

3. The method of manufacturing the actuator device according to claim 1 , wherein a conductive adhesive is applied to an area of the plurality of wires which is exposed from the insulating layer.

4. The method of manufacturing the actuator device according to claim 3 , wherein the conductive adhesive is not applied to an edge portion, of the base, including the cut edge of the base.

5. The method of manufacturing the actuator device according to claim 4 , wherein a heater is pressed against the wire member such that the wire member is joined to the actuator.

6. The method of manufacturing the actuator device according to claim 5 , wherein the heater is pressed against the wire member such that the conductive adhesive flows toward the edge portion of the base.

7. The method of manufacturing the actuator device according to claim 1 , wherein each of the plurality of test contacts has a width greater than that of each of the plurality of wires.

8. The method of manufacturing the actuator device according to claim 1 , wherein a probe is brought into contact with each of the plurality of test contacts to perform the conduction test for a corresponding one of the plurality of wires.

9. The method of manufacturing the actuator device according to claim 8 , wherein the plurality of wires include at least one dummy wire, and the conduction test of each of the at least one dummy wire is performed using a corresponding one of the plurality of test contacts.

10. The method of manufacturing the actuator device according to claim 1 , wherein the base is cut by shearing using two metal molds.
