A hot pressed member comprises: a predetermined chemical composition (in particular, low C of 0.090% or more and less than 0.30% and high Mn of 3.5% or more and less than 11.0%); a first region having: a microstructure including a martensite phase of 80.0% or more in volume fraction and a retained austenite phase of 3.0% or more and 20.0% or less in volume fraction; and a dislocation density of 1.0×1016/m2 or more; and a second region having a microstructure including a ferrite phase of 30.0% or more and 60.0% or less in volume fraction, a retained austenite phase of 10.0% or more and 70.0% or less in volume fraction, and a martensite phase of 30.0% or less in volume fraction.
