Because a first planar part (27) at an outer peripheral part of a first formed body (26) provided through a first drawing step is held by a blank holder (33) during its bending to provide an L-shaped cross-section part (36) in a second drawing step, no wrinkles will develop at a vertical part (38). Because an unnecessary outer part (44) of a flange part (46) is cut off in a trimming step, the width of the flange part is narrowed. By virtue of the narrowed width, no wrinkles will develop during bending of the flange part.

As a result, flexibility in the design of panel parts, which are formed by pressing the panel material into shapes, is increased.
