PROBLEM TO BE SOLVED: To provide a press formed member, and a press forming method excellent in shape freezing property. SOLUTION: In the press formed member, a wave shape Wb11 having the wave depth D of≤0.3 m substantially in the vertical direction with respect to the passing direction S is formed on a part subjected to the bend-bend back deformation by passing a stock metal plate W under the press forming through a ridge forming part, for example, a longitudinal wall part Wb1 of a drawn press forming member Wb after the release. The Wave plate shape Wb1 is press formed by engraving linear uneven shapes 111, 112 and 211, 212 with the unevenness engaged with longitudinal wall forming parts 11, 21 of a punch 1 and a die 2 as its forming faces.
