Abstract
A fastener stringer for a concealed slide fastener in which a knitted fastener tape has a tape main body portion and a doubled-tape portion that is formed by extending in a width direction from the tape main body portion and being folded back, wherein at least a chain stitch yarn is included in each wale forming the tape main body portion, and wales forming the doubled-tape portion have at least one wide wale having a second wale width that is greater than the first wale width of the wale forming the tape main body portion. The doubled-tape portion of the fastener tape can thereby be provided with superior flexibility.
