To provide an artificial nipple which a baby is less unwilling to use by making it have a touch and a friction closer to that of a mother's real nipple on the baby's tongue.

The surface micro-shape of this artificial nipple, designed to make it feel closer to the human skin, is provided with narrow channels running various directions in a way that its pattern has micro projections shaped like a triangle or polygon that are arranged in order when seen from above, or has small protrusions and small dimples that are extensively arranged. Thereby, it can give a similar touch and friction on the baby's tongue to that of the mother's real nipple, while keeping its flexibility, increasing flexibility and making plasticity compatible therewith.
