Patent ID: 8735737

Claim:
A substrate comprising: a substrate base having a first surface and a second surface located opposite the first surface; a plurality of first pads arranged in a pattern on the first surface; and a plurality of leads respectively having a flexible part with a generally U-shape, a first end provided on the flexible part, electrically connected to a corresponding one of the plurality of first pads, and a second end provided on the flexible part, located a predetermined distance away from the first end relative to the first surface along a direction perpendicular to the first surface, wherein the first and second ends are substantially aligned in the direction perpendicular to the first surface in a first state in which the second end is pushed towards the first end by a target object and the flexible part is deformed thereby in order to electrically connect the substrate to the target object via the second end of each of the plurality of leads, wherein the flexible part, whose a first end part is electrically connected to the corresponding one of the plurality of first pads, is offset from the corresponding one of the plurality of first pads in a direction parallel to the first surface in the first state and in a second state in which the second end is not pushed towards the first end by the target object and the flexible part is not deformed, wherein each of the plurality of leads includes a first support obliquely extending towards the first surface from the first end part of the flexible part, and a first connection part extending from the first support part and connecting to the first end, wherein the first support part forms an acute angle with respect to a plane that is parallel to the first surface and passes a surface of the first connection part opposing the first surface in the second state, in order to avoid contact between the first surface of the substrate base and the first support part in the first state in which the flexible part is deformed, wherein each of the plurality of leads includes a second support part obliquely extending towards the target object from a second end part of the flexible part, opposite to the first end part of the flexible part, in the second state, and a second connection part extending from the second support part and connecting to the second end, wherein the second connection part includes a projecting part obliquely extending towards the target object from the second support part in the second state, and a contact part having a rounded shape extending from the projecting part and reaching the second end, wherein the projecting part has two ends thereof integrally formed on the second support part and the contact part, respectively, and wherein the second support part projects towards the first end in the first state, in order to avoid contact between the target object and the second support part.
