A connector, and printed circuit board foot pattern for a connector which can efficiently transmit a high-speed differential signal are provided. In a connector 1, a contact group 30 includes at least paired adjacent signal contacts SC-SC, and non-paired contacts GC which are placed on both adjacent sides or one adjacent side of the paired signal contacts. The contacts are arranged so that the distance W1 between the paired signal contacts SC-SC is shorter than the distance W2 between adjacent signal and non-paired contacts SC-GC, thereby enhancing the differential coupling force between the paired signal contacts SC-SC.
