PROBLEM TO BE SOLVED: To provide switch structure capable of ensuring waterproofness, simplifying structure, reducing a manufacturing cost, and reducing thickness. SOLUTION: An opening 10a is formed in an outer case 10, and button 11 is inserted into the opening 10a. A recess 11a having an opening inside of the outer case 10 is installed, and a magnet 12 is housed inside the recess 11a. A magnetic fluid is arranged between the button 11 and an opening edge of the outer case 10, and this magnetic fluid 14 is held on the outer circumferential surface of the button 11 by the magnetic force of the magnet 12 housed inside the button 11. |
