PROBLEM TO BE SOLVED: To provide a vibration linear actuator which is advantageous for miniaturization. SOLUTION: This vibration linear actuator reciprocally drives two or more movable elements 2 by a stator 1. The movable elements are supported with a fixed section 10 of a chassis 3 on which the stator is fixed and a joint board 9 jointed to the movable elements 2, while they are allowed to move freely reciprocally. The fixed section 10 is obtained by covering a metal part 13 with a molded item 14. The molded item 14, which is for jointing the joint board, is placed on a section where the thickness or width placed on the outer face of a metal part 13 is reduced, or on a through hole 62 bored in the metal part 13. The molded item 13 can be an item which does not increase the thickness or width. COPYRIGHT: (C)2007,JPO&INPIT
