Patent ID: 7950963

Claim:
A connector, comprising: a wiring board; a lead configured to connect the wiring board electrically to an external board; and a conductive layer configured to connect the lead to the wiring board so as to allow the lead to move in predetermined directions relative to the wiring board when the conductive layer is melted, wherein the lead includes a first region, a second region, and a third region, the first region being in contact with the conductive layer and being sandwiched between the second region and the third region in directions parallel to the predetermined directions, the second region and the third region being lower in wettability with respect to a liquid melt of the conductive layer than the first region, the wiring board includes a first region and a pair of second regions, the first region being in contact with the conductive layer and being sandwiched between the second regions in the directions parallel to the predetermined directions, the second regions being lower in wettability with respect to the liquid melt of the conductive layer than the first region, and a center of the first region of the lead is offset in a direction parallel to the predetermined directions and away from the external board relative to a center of the first region of the wiring board.
