Claim:
A card edge connector comprising: a plurality of contacts; a housing configured to hold the plurality of contacts arranged in a first direction; and a pair of arm members held on the housing so as to extend along a second direction perpendicular to the first direction, each of the arm members including a latch portion and an interference portion, wherein: the latch portion is configured to engage with a side edge of a card when the card is connected to the card edge connector; and the interference portion is configured to interfere with the side edge of the card in the first direction so as to prevent the latch portion from engaging with the side edge of the card when the card is improperly connected to the card edge connector, the interference portion projecting inwardly in the first direction beyond the latch portion; each of the arm members is produced by punching a sheet metal and bending the punched sheet metal; and the interference portion is produced so as to extend in a third direction perpendicular to both the first direction and the second direction after extending inward in the first direction by bending the punched sheet metal about an axis extending in a direction that is perpendicular to the third direction and is oblique to both of the first direction and the second direction.
