PROBLEM TO BE SOLVED: To provide a vibration welder which is improved in vibration welding accuracy and has a miniaturized size. SOLUTION: In the inside of the structure formed of a fixed frame 101, a movable frame body 102 and a pair of leaf springs 103, 104 having lattice holes, a pair of electromagnets 110, 111, which are arranged so that a predetermined distance may be in between and the attracting faces may be opposite and which are alternately electrified, are held in the state of being fixed on the fixed frame 101. Also in the above structure is held a movable piece 112 which is arranged between a pair of the electromagnets 110, 111, the lower part of which is fixed on the movable frame 102 and which is alternately attracted to a pair of the electromagnets 110, 111 to produce vibration. Further are furnished leaf springs 106, 107 whose one end is fixed on the side of the fixed frame 101 that makes the side of the structure and whose other end is fixed on the side of the movable frame body 102.
