PROBLEM TO BE SOLVED: To improve attachment strength of a handle to a bottle body by providing both attaching arms on and under a grip and also by providing a locking protrusion including a protrusion at tips of both upper and lower attaching arms. SOLUTION: Both attaching arms 32, 33 are provided on and under a grip 31, while a protrusion 35 is provided at a tip of a locking protrusion 34 provided at tips of both attaching arms 32, 33. If the handle 3 is attached to be buried in a wall face 21 of a recess formed on a side face of a bottle body, anchor effects to the wall face 21 by presence of the protrusion 35 can improve attachment strength of the handle 3. In particular, when the handle 3 is insert-molded and attached to the bottle body, the locking protrusion 34 is attached to face upward whereby resistance to slip is reduced as a lower face of the lower attaching arm 33 has no protrusion. Therefore, coupling between the lock 34 and the wall face 21 at the time of molding can be smoothly performed.
