The invention provides an arc-shaped ceramic shell and a manufacturing method thereof, and the manufacturing method comprises the following steps: carrying out ball milling on ceramic powder, an adhesive, a dispersing agent, a plasticizer, a solvent and the like according to a certain proportion for a certain time to form ceramic slurry; after the ceramic slurry is subjected to tape casting, a tape casting strip material is formed; carrying out punching and cavity punching treatment on the casting belt material to obtain a green ceramic belt; filling a hole punched by the green tape with metal slurry by using a hole filling machine; printing a circuit on the green tape; each green tape is compacted in an isostatic pressing mode, and the adopted isostatic pressing pressure is gradually reduced according to the sequence of the stacked layers; sequentially stacking the compacted green ceramic tapes according to a stacking hierarchy sequence; cutting the green ceramic body into green ceramic body units; and sinte
