PROBLEM TO BE SOLVED: To provide a nipple for feeding bottles having advantages of the conventional nipple, allowing a user to suckle a baby regardless of its location and having an elongation characteristic approximate to the characteristic of the mother's nipples. SOLUTION: This nipple for feeding bottles includes: a hollow dome-like trunk section which has a flange-like base to be connected to a feeding bottle, at its lower face; a bellows-like extensible trunk section which is consecutively provided from the trunk section and has a uniform thickness; and a nipple section which is consecutively provided from the extensible trunk section and has a suckling opening at its tip end. The extensible trunk section is formed with: a plurality of concentric and ring-shaped projections whose diameters become smaller as their going upward, at its outside circumferential face; and recesses which are so configured that the inside faces corresponding to the respective projections have a same wall thickness at any part; so as to have the bellows structure whose both outside and inside faces consist of the smooth and wavelike shapes and which is tapered and has the uniform thickness.
