An apparatus for rolling and forming a food dough comprising: a rolling roller configured to roll out a block of food dough placed on a table into a flattened shape; and a frame unit having an inner circumferential surface configured to face the rolling roller, wherein: the rolling roller is configured to revolve relative to the table around a revolving axis, and rotate relative to the table around a rotation axis of the rolling roller; the rolling roller is configured to move relatively towards and away from the table; the rolling roller comprises a first portion having a substantially conical or frustum shape extending in a rotation axial direction from a first base end thereof to a first distal end thereof, the first distal end being closer to the revolving axis than the first base end In a revolving radial direction with respect to the revolving axis, and the first distal end having a diameter smaller than that of the first base end; the frame unit is provided outside of a revolving locus of the first portion of the rolling roller; the inner circumferential surface of the frame unit comprises an upper side portion and a lower side portion; and the rolling roller further comprises a second portion having a substantially frustum shape extending from a second base end connected to the first base end to a second distal end in the rotation axial direction opposite the first distal end, the second portion has a diameter decreasing towards the second distal end such that a second generatrix of the second portion located at a lowest position thereof is inclined upwards towards the second distal end; characterized in that the lower side portion of the inner circumferential surface of the frame unit is farther from the revolving axis than the upper side portion with respect to the revolving radial direction; and in that the inner circumferential surface of the frame unit is configured to face the second generatrix. a rolling roller configured to roll out a block of food dough placed on a table into a flattened shape;
