Claim 6:
7. A MEMS device, comprising:
a substrate including an element and a connection wiring electrically connected to the element; and
a connection portion electrically connected to the connection wiring and formed of a eutectic alloy of a first metal and a second metal,
wherein a width of the connection wiring is smaller than a width of the connection portion when a main surface of the substrate is viewed in a plan view of the substrate,
wherein the substrate further includes a contact electrode that electrically connects the connection wiring and the element,
wherein a length of the connection wiring from the connection portion to the contact electrode is three times or more of the width of the connection wiring in the plan view, and
wherein the connection wiring further includes an electrode pad between the connection portion and the element in the plan view.
