A manufacturing method for a flexible mold, the flexible mold comprising: a base; and an uneven layer formed on the base, the manufacturing method comprising: a transfer step of sandwiching a molding material between the base and a master mold so that the uneven layer obtained by transferring an uneven pattern of the master mold to the molding material is formed on the base, wherein the base comprises: a glass sheet; a resin sheet; and a bonding layer configured to bond the glass sheet and the resin sheet to each other, and the resin sheet protrudes from the glass sheet characterized in that the glass sheet and the resin sheet each protrude from the bonding layer, and wherein the resin sheet is bonded to only one main surface of the glass sheet through intermediation of the bonding layer. the flexible mold comprising: a base; and an uneven layer formed on the base, the manufacturing method comprising: a transfer step of sandwiching a molding material between the base and a master mold so that the uneven layer obtained by transferring an uneven pattern of the master mold to the molding material is formed on the base, wherein the base comprises: a glass sheet; a resin sheet; and a bonding layer configured to bond the glass sheet and the resin sheet to each other, and the resin sheet protrudes from the glass sheet characterized in that the glass sheet and the resin sheet each protrude from the bonding layer, and wherein the resin sheet is bonded to only one main surface of the glass sheet through intermediation of the bonding layer. a base; and an uneven layer formed on the base, the manufacturing method comprising: a transfer step of sandwiching a molding material between the base and a master mold so that the uneven layer obtained by transferring an uneven pattern of the master mold to the molding material is formed on the base, wherein the base comprises: a glass sheet; a resin sheet; and a bonding layer configured to bond the glass sheet and the resin sheet to each other, and the resin sheet protrudes from the glass sheet characterized in that the glass sheet and the resin sheet each protrude from the bonding layer, and wherein the resin sheet is bonded to only one main surface of the glass sheet through intermediation of the bonding layer. a transfer step of sandwiching a molding material between the base and a master mold so that the uneven layer obtained by transferring an uneven pattern of the master mold to the molding material is formed on the base, wherein the base comprises: a glass sheet; a resin sheet; and a bonding layer configured to bond the glass sheet and the resin sheet to each other, and the resin sheet protrudes from the glass sheet characterized in that the glass sheet and the resin sheet each protrude from the bonding layer, and wherein the resin sheet is bonded to only one main surface of the glass sheet through intermediation of the bonding layer. a glass sheet; a resin sheet; and a bonding layer configured to bond the glass sheet and the resin sheet to each other, and the resin sheet protrudes from the glass sheet characterized in that the glass sheet and the resin sheet each protrude from the bonding layer, and wherein the resin sheet is bonded to only one main surface of the glass sheet through intermediation of the bonding layer.
