To provide an infant-feeding bottle which allows stable intake of milk or the like regardless of a feeding operation for an infant.SOLUTION: An infant-feeding bottle 10 comprises a bottle body 1 for holding a liquid and a spout part 2 arranged on one end of the bottle body 1, the spout part 2 is formed of a rigid resin. A tip of the spout part 2 has an opening whose opening space is 8 mmor smaller. The spout part 2 is formed of a rigid resin. When the infant-feeding bottle is used for an infant, extremely large force is applied to the spout part 2 by the feeding operation for an infant. Since the spout part 2 is formed of a rigid resin, an opening 3 on a tip is not deformed even in the feeding operation for an infant, for allowing an infant to stably take the milk or the like.SELECTED DRAWING: Figure 2【課題】乳児の哺乳動作の如何に関わらず、安定したミルク等の摂取が可能な哺乳瓶を提供する。【解決手段】液体を保持する瓶本体１と瓶本体１の一端に配置される飲み口部２とを備え、飲み口部２は硬質樹脂からなり、飲み口部２の先端には、開口面積が８ｍｍ２以下の開口を有する哺乳瓶１０である。飲み口部２は、硬質樹脂からなる。乳幼児が哺乳瓶を用いる際、飲み口部２には乳幼児の哺乳動作により非常に大きな力が加わる。飲み口部２を硬質樹脂とすることで、乳幼児の哺乳動作においても先端の開口３が変形せず、安定してミルク等の摂取が可能となる。【選択図】図２
