Claim 0:
1. A mold for producing a hydrogel support for a 3-dimensional (3D) cell culture, the mold comprising:
an upper mold comprising a base and a plurality of upper unit molds protruding downward from the base to form accommodating portions of a female type corresponding to shapes of hydrogel supports, having through holes at bottoms thereof, and patterned at a lower portion of the base;
a lower mold where a plurality of lower unit molds are patterned, the plurality of lower unit molds formed in a female type to respectively accommodate the plurality of upper unit molds protruding downward and having sealed lower portions; and
an ejecting unit for separating, from the accommodating portions of the plurality of upper unit molds, the hydrogel supports that are coagulated after being inserted into the through holes respectively formed in the plurality of upper unit molds,
wherein the ejecting unit comprises:
a head portion having elasticity; and
a stem portion connected to a lower portion of the head portion,

wherein the head portion is formed to have a larger area than the stem portion,
wherein an area of the head portion gradually increases from one end to the other end of the head portion,
wherein each of the through holes of the upper mold has a size corresponding to the other end of the head portion so that the other end of the head portion is configured to pass through each through hole.
