PROBLEM TO BE SOLVED: To provide a wiring circuit substrate capable of preventing the separation of a metal support substrate by improving the adhesiveness of the metal support substrate with a simple configuration at the end rim of an opening formed on the metal support substrate. SOLUTION: In order to reduce the transmission loss of a conductor pattern 5 in a suspension substrate 1 with a circuit, a metal foil 6 buried in a base insulating layer 3 is formed as a pattern equipped with a first metal foil 9, and a second metal foil 10 surrounding the first metal foil 9 with a gap S1, while an opening unit 7 is formed on the metal support substrate 2 so that the opening end rim 8 thereof is arranged in the gap S1.

Abstract:
PROBLEM TO BE SOLVED: To provide a contact member ensuring good conductive connection between an electronic component and a mother board even when the electronic component is shrunk, and to provide its fabrication process. SOLUTION: Resilient arms 5b, 6b, 7b of contacts 5, 6, 7 can be deformed easily and surely utilizing internal stress. The resilient arm of the contact can be deformed easily and surely utilizing internal stress even if the contact is shrunk in accordance with shrinkage of an electronic component 2. Since the resilient arm deforms resiliently and appropriately and a plurality of stacked resilient arms can function as a resilient contact, distortion caused by difference in thermal expansion coefficient between the electronic component and the mother board 1 can be absorbed appropriately by the contact, and conductive connection between the electronic component 2 and the mother board can be ensured even if a plurality of resilient contacts cause a slight positional shift of the electronic component.
