<p>A fastener tape (10, 20) according to the invention includes a tape main body portion (12, 22) and an element attachment portion (11, 21) in which a core thread (15, 25) is knitted. The tape main body portion (12, 22) includes a first tape main body portion region (12a, 22a) at the side of the element attachment portion (11, 21) and a second tape main body portion region (12b, 22b). A wale interval between a wale (W2) of the element attachment portion (11, 21) adjacent to the first tape main body portion region (12a, 22a) and a wale (W3 to W5) constituting the first tape main body portion region (12a, 22a) is narrower than that of the second tape main body portion region (12b, 22b). Therefore, while the flexibility of the second tape main body portion region (12b, 22b) is ensured, a tape strength and an abrasion resistance of the first tape main body portion region (12a, 22a) and a region of the element attachment portion (11, 21) at the side of the tape main body portion are improved, and further, when a fastener element (2) is formed, this prevents resin leakage through knitted loops of the element attachment portion (11, 21).</p> |
