Abstract
A method of manufacturing a sheet metal flame includes a step of forming at least one drawn portion in a frame main body formed into a flat plate shape, and a step of engraving groove portions into a linear shape in the frame main body at constant distances from outer edge portions of the at least one drawn portion so as to sandwich the at least one drawn portion between at least opposing sides.

A method of manufacturing a sheet metal frame, comprising:
- a step of forming at least one drawn portion in a frame main body formed into a planar shape such that the at least one drawn portion projects in a surface direction from a planar portion of the frame main body;
- and
- a step of, after forming the at least one drawn portion, engraving, from a projecting side of the at least one drawn portion, groove portions stretched to have a linear shape in the planar portion of the frame main body at a distance of 5 to 10 mm from a boundary portion between the planar portion and the at least one drawn portion so as to surround an entire region of at least one drawn portion.
