Pressed product

Abstract

The invention offers a pressed product (F) produced by press-forming a metal plate (1). The pressed product (F) has a peripheral surface that has a corner portion (12) connecting two surfaces in the peripheral surface. The corner portion (12) has an outside corner radius R that is equal to or smaller than the thickness “t” of the metal plate (1). That is, the pressed product (F) has the sharp corner portion (12).

Description

RELATED APPLICATIONS[0001]This application is the U.S. National Phase under 35 U.S.C. §371 of International Application No. PCT / JP2009 / 062855, filed on Jul. 16, 2009, which in turn claims the benefit of Japanese Application No. 2008-239712, filed on Sep. 18, 2008, the disclosures of which Applications are incorporated by reference herein.TECHNICAL FIELD[0002]The present invention relates to a pressed product to be used, for example, for the housing of a portable electronic device, particularly to a pressed product having a sharp corner portion.BACKGROUND ART[0003]Metal such as aluminum or its alloy is used as the material for the housing of a portable electronic device or the like, such as a cellular phone and a note-book-type personal computer. Generally, in comparison with resin, metal has a higher strength and is more resistant to an impact.[0004]As the foregoing material for the housing, magnesium alloys have been used which are formed by adding various elements to magnesium.
