Title: Inside-coated metal container and its manufacturing method

Abstract: The durability of the inside coating to the deformation processing in the post-processing of the inside-coated metal container having corrosion-resistivity is improved to reduce minor cracks and peelings as far as possible. In an inside-coated metal container 10 in which a high-degree of deformation processing is applied to the vicinity of an opening of one end after coating the inner surface, the coating films formed by the coating have the first layer 12 with high deformation processing durability laid on an area where the high-degree deformation processing is applied and the second layer 13 with high corrosion resistivity laid on the entire inner surface including the first layer of the metal container. The first layer 12 is made of phenolic epoxy resin coatings containing little phenol component and no pigment, and the second layer 13 is made of phenolic epoxy resin coatings containing much phenolic component and pigment.
