A method for producing a center pillar reinforcement by means of press-forming of a metal blank , the center pillar reinforcement comprising a body which is lengthy and partially curved substantially in a bow shape and two substantial T shape sections formed at both end portions in the longitudinal direction of the body , and thereby a panel having a substantial I shape in a plan view being formed, the body having a substantially hat-shaped cross section formed by a curved and lengthy top sheet , two vertical walls connecting with both edge portions in the width direction of the top sheet , and two outward flanges connecting with the respective two vertical walls , the two substantial T shape sections each having a top sheet , and two curved vertical walls connecting with the top sheet , and the two curved vertical walls of at least one of the two substantial T shape sections each having a height which decreases gradually toward a direction directed from the body to the substantial T shape section , characterized in that the center pillar reinforcement is produced by performing a first step for producing a first intermediate formed product by press-forming the blank by using a first press-forming device for drawing, the device comprising a die , a blank holder for clamping the blank together with the die , and a punch for pressing the blank into the die , the first intermediate formed product having a body section and portions that are formed into the two substantial T shape sections , the body section being formed by some parts of the top sheet and each of the two vertical walls in the body, and a part of the top sheet and each of the two vertical walls in one substantial T shape section of the two substantial T shape sections , and the portions which are formed into the two substantial T shape sections excluding the some parts of the top sheet and each of the two vertical walls in the one substantial T shape section, and a second step for, by using a second press-forming device for bend-forming, the device comprising a punch , a pad having a butting surface facing to the protrusion of the punch , and a die for pressing the first intermediate formed product onto the punch , pressing the first intermediate formed product in a state in which at least part of each of portions formed in the two substantial T shape sections of the intermediate formed product is clamped by the pad and the punch , wherein, in the case where the uppermost position in a region in the longitudinal direction where the body section is formed is defined as a longitudinal direction 0% position, the value of the longitudinal direction % is defined so as to be increased with the decrease in the longitudinal direction, and the lowermost position in the region in the longitudinal direction is defined as a longitudinal direction 100% position, the height of the vertical walls in the body section formed in the first intermediate formed product by the first step is at most 20% of the height of the vertical walls of the center pillar reinforcement at the longitudinal direction 0% position; at least 60% of the height of the vertical walls of the center pillar reinforcement at the longitudinal direction 20 to 60% positions, and at most 20% of the height of the vertical walls of the center pillar reinforcement at the longitudinal direction 100% position. <EOS>
