Abstract:
PROBLEM TO BE SOLVED: To provide an optical device including a movable body holding a lens and a fixed body movably holding the movable body, in which even when the device is miniaturized, the movable body can be properly moved and which can reduce the manufacturing cost of a magnet for driving for moving the movable body.SOLUTION: An optical device 1 includes a movable body 2 holding a lens for photographing, a fixed body 3 movably holding the movable body 2, a magnet for driving 18 and a coil for driving 17 for moving the movable body 2 relatively to the fixed body 3, and metal members 24 and 25 fixed to the magnet for driving 18. The coil for driving 17 fixed to the fixed body 3 and the magnet for driving 18 fixed to the movable body 2 are arranged to face each other across a predetermined gap. The magnet for driving 18 and the metal members 24 and 25 are joined to each other by tin layers 26 and 27 formed by melting and solidifying tin foil arranged between the magnet for driving 18 and the metal members 24 and 25.
