The invention discloses a highly flexible relay reed component comprising a moving reed and an armature; the moving reed comprises a reed body and at least one reinforcing reed; the reinforcing reed is connected to the upper surface of the reed body and the length of the reed is shorter than the reed body; the right end of the reed body is provided with a movable contact; and the end, closer to the moving contact, of the reed body protrudes outside from the right end of the armature; the left ends of the reed body and the reinforcing reed are both bent downward towards the direction of the armature; the bent portions of the reed body and the reinforcing reed are both in circular arc structures; and the bent portions of the reed body and the reinforcing reed are provided with elongated through grooves along the length direction. The invention also discloses a relay comprising the moving reed component. According to the highly flexible relay reed component and relay, the reed portion hashigh structural flexibility, and has a stable motion process when the component moves, and the limit of the moving reed is stable in the relay.
