PROBLEM TO BE SOLVED: To avoid making an excessive electric current flow into a controller and the like which applies the electric current to a heater, by an induction current flowing into the heater of a windshield when it is struck by lightning.SOLUTION: A windshield 10 of an aircraft includes a plurality of conductive layers 21, 22 and 23 that are arranged along an in-plane direction of the windshield 10 and wire-connected to one another. The plurality of conductive layers 21, 22 and 23 are heaters that are supplied with a three-phase alternating current to generate heat, and wire-connected so that each induction current Iinduced by a magnetic field H associated with a lightning current Ican be circulated among the conductive layers 21, 22 and 23.SELECTED DRAWING: Figure 2 |
