<p>The present invention provides a fastener stringer for a concealed type slide fastener having an excellent concealing performance of blocking fastener element rows from being seen from a front surface side even when a strong lateral pulling force is applied when right and left fastener element rows are coupled with each other, wherein the fastener stringer (1) of the present invention comprises: a fastener tape (2) having a tape main body portion (4) and an element attaching portion (5); and an fastener element row (3) woven into the element attaching portion (5), a side edge of the tape main body portion (4) being folded back into a U shape and a coupling head (7) of the fastener element row (3) being projected outward, the element attaching portion (5) being provided with a plurality of upper and lower fixingwarp yarns (23, 24) which run on upper and lower leg portions (8, 9) of an element (6) and a plurality of tightening warp yarns (25) which run so as to stride over the upper leg portion (8) and the lower leg portion (9) alternately while intersecting one another between the upper and lower leg portions (8, 9), a total fineness of the lower fixing warp yarns (24) running on a side of the coupling head (7) with respect to the tightening warp yarns (25) is higher than a total fineness of the upper fixing warp yarns (23) running on the side of the coupling head (7) with respect to the tightening warp yarns (25).
