To provide a rubber molding excellent in the physical property by utilizing characteristics of the rubber, and its manufacturing method.SOLUTION: The rubber molding is formed by cross-linking rubber compositions having rubber polymers, zinc oxide, vulcanizing accelerator and sulfur based vulcanizer. When a measurement range of a length of 1 μm in cross section of rubber molding is line analyzed by an energy dispersive X-ray analysis apparatus, about Zn amount, when the maximum value of the intensity is set to 1, a ratio of a part having the intensity ration of the Zn of 0.2 or smaller is 20% or larger and 95% or smaller of the measurement range. A manufacturing method of rubber molding comprises: a raw material latex manufacturing step for manufacturing a raw material latex containing rubber latex, zinc oxide, vulcanizing accelerator and sulfur based vulcanizer; a step of drying of blowing the raw material latex on a surface of the heated substrate to dry to obtain the rubber composition; and a step of crosslinking the rubber composition.SELECTED DRAWING: None
