PROBLEM TO BE SOLVED: To provide an optical deflector of a two axis oscillation type having a very simple structure. SOLUTION: A magnetic spherical body 13 held between the central part of the back face of a mirror part 11e formed in a mirror body 11 and the inner peripheral face of a hemispherical hole part 12b with bottom formed on a mirror supporting base 12, is moved along the inner peripheral face of the hemispherical hole part 12b of the mirror supporting base 12 with a magnetic suction force, the mirror part 11e is two dimensionally oscillated in an X-Y plane, the price is reduced because of a simple structure, and the mirror part 11e can be tilted with a large deflection angle with a low power.
