Electroformed mold and manufacturing method therefor

It includes an electroformed shell 6 , which has a molding surface 60 and is formed by electroforming processing, a media flow path 2 for circulating a heat medium so as to perform temperature adjustment on the molding surface 60 formed in the electroformed shell 6 , a backing member 71 with which the electroformed shell 6 is backed, and media conveying paths 74 , respectively provided in an upstream-side end portion 21 and a downstream-side end portion 21 , for flowing a heat medium into or out of the media flow path 2 . A connecting jig 1 for connecting the media flow path 2 and the media conveying paths 74 is embedded in the electroformed shell 6 . The connecting jig 1 includes a cavity portion formed therein, an opening hole having a cross-sectional shape which is substantially the same as the shape of a radially cross-section of the media flow path 2 , and a connecting hole having a cross-sectional shape which is substantially the same as the shape of an outside diametrical cross-section of a pipe member 741 constituting each of the media conveying paths 74 . The opening hole and the connecting hole are communicated with each other through the cavity portion.
