PROBLEM TO BE SOLVED: To provide an electric fan for attaining purification, deodorization, antibacterial state, fungicidal property and antifouling property of air even under a situation of less ultraviolet ray amount.SOLUTION: A blade 30 of an electric fan includes stress light emitting material for emitting light of ultraviolet rays through stress generated at the blade 30 with air pushed out when the blade 30 of the electric fan is rotated, air is pushed forward and photocatalyst of TiOgroups. The stress light emitting material is at least one type selected from a group of materials expressed by CaSrAlSiO(0.2≤x≤1), SrAlO, SrBaAlO(0.8≤y≤1), SrMgSiO, Sr(PO),Ba(PO), these materials show that 0.1 mol% to 10 mol% of alkaline-earth metal ion constituting the materials is replaced with Ce ion. |
