An object of the present invention is to provide an artificial nipple in which a nipple tip section can sufficiently reach the sucking fossa and can be appropriately squashed, so that a nursing operation can reliably take place in that state, and to provide also a nursing container and a pacifier toy that uses that artificial nipple. The artificial nipple is configured overall as a substantially conical hollow body, and has: a base section that widens to match an attachment object; an areola section that extends while narrowing gradually; and a nipple section that extends without widening halfway up to a tip and while narrowing slightly and gradually at a diameter-narrowing rate that is smaller than the diameter-narrowing rate of the areola section. The areola section has a wall thickness greater than that of the nipple section, the nipple section is set to have a length sufficient to reach the sucking fossa, and a wall thickness at a boundary between the areola section and the nipple section is smaller than that of the areola section but greater than that of the nipple section, as a result of which a band-like weakened section is formed along the circumference of that site.本發明之課題在於提供一種乳頭前端部可充分地到達哺乳窩而可適當地擠扁,且於該狀態下可確實地進行哺乳運動之人工乳頭及使用其之哺乳器暨奶嘴玩具。該人工乳頭係整體為大致圓錐狀之中空體,其包含:底部,其直徑對應於安裝對象而擴大;乳暈部,其直徑漸漸縮小而延伸;以及乳頭部,其直徑不在到達前端的途中擴大,且直徑以小於上述乳暈部之上述縮徑率之縮徑率,一點一點漸漸縮小而延伸,並且,上述乳暈部作成具有厚度大於上述乳頭部厚度之厚壁,上述乳頭部之長度設定為足以到達哺乳窩之充分長度,並於上述乳暈部與上述乳頭部之邊界,設有藉由使厚壁小於上述乳暈部、且使厚壁大於上述乳頭部,而沿著該部位之圓周形成為帶狀之脆弱部。
