The invention discloses a body armor. The body armor comprises a body armor body which consists of a bottom lining layer and a protecting layer, wherein a silica gel layer is arranged between the bottom lining layer and the protecting layer in a filling and sewing manner; the protecting layer comprises a front protecting layer and a rear protecting layer; a first inserting plate layer and a second inserting plate layer are correspondingly fixedly mounted on the front protecting layer and the rear protecting layer; the first inserting plate layer comprises a chest protecting inserting plate layer, a waist protecting inserting plate layer and shoulder protecting inserting plate layers; an abdomen protecting inserting plate layer which is in a shape of a wedge being thick in front and thin in back is fixedly mounted on the side surface of the chest protecting inserting plate layer. According to the body armor, hard inserting plates are used and can effectively prevent a human body from impact injury caused by a bullet and a shrapnel and the like, and the pressure is reduced; the inserting plates are in a combination mode, so that the flexibility is extremely high while the bulletproofing performance is achieved; the shrapnel shot to the human body is deviated from the human body and slides out from the human body along the bulletproofing materials according to the mechanics guiding theory, thus the impacting force of the bullet to the human body can be reduced, and the human body is greatly prevented from being injured.
