CONNECTOR FOR ELECTRIC CIRCUIT CONNECTION

摘要

PROBLEM TO BE SOLVED: To provide a connector for electric circuit connection without causing electro-migration even when a pitch interval between contact patters is narrow.

SOLUTION: The connector is provided with a first connector 10 provided with the contact pattern 30 on an insulating substrate 20 and an anisotropic conductive film 31 on the contact pattern 30, and a second connector 50 provided with a resilient contact 61 having resiliency. The connector connects the resilient contact 61 and the contact pattern 30 of the first connector 10 through the anisotropic conductive film 31 by the resilient force of the resilient contact 61 of the second connector 50 by engaging both the connectors 10 and 50. The anisotropic conductive film 31 has the distribution of conductive powder 313 and insulating powder 315 in a binder resin 311. The conductive powder 313 contains conductive powder of a larger particle diameter larger than film thickness of the anisotropic conductive film 31. The insulating powder 315 has hardness collapsed by the resilient contact force of the resilient contact 61. The average particle diameter of the insulating powder 315 is equal to or larger than that of the conductive powder 313.
