PROBLEM TO BE SOLVED: To provide an omnidirectional sensor capable of simultaneously extracting the direction of an azimuthal magnetic needle operated by a terrestrial magnetism and the inclination to the direction of gravity by a simple method. SOLUTION: In this omniderectional sensor, the surface of a sphere, inside of which a directional magnet 16 and a weight 17 are present, is reflection-treated and the surface of a sphere, enclosing the sphere, is scattering-treated, while an absorption pattern which suitably prohibits the light to transmit is arranged on the surface. This sphere is floated in a light shielding housing 13 which is filled with a transparent liquid and has a transmission window 12 on an incident side and a transmission window 19 on an emitting side to convert the light emitted from the transmission window 19 on the emitting side to electric signals by a photoelectron conversion element 18.
