PROBLEM TO BE SOLVED: To provide a vibrational energy absorber in which the rigidity of the portion of the structure receiving a resistant force and the restoring force of a returning means need not be increased, and to provide a structure having the vibrational energy absorber. SOLUTION: This vibrational energy absorber 1 comprises a reciprocating member 2, capable of reciprocating the positive and negative maximum displacement position D±max relative to origin O in H direction, a damping force generating means for generating a damping force R against the reciprocating motion of the reciprocating member 2 in the H direction, and a control means 4 for generating a damping force R in the damping force generating means 3 in the movement thereof, in the H direction from the positive and negative maximum displacement position D±max to the origin O in the reciprocating motion of the reciprocating member 2 in the H direction and controlling the damping force generating means 3 so that the damping force R will not be generated in the damping force generating means 3 in the movement of thereof from the origin O, followed by the movement thereof in the H direction to the positive and negative maximum displacement position D±max.
