[Object] To provide a fan blade, an engine, and a structure with anti-icing and de-icing functions, which are capable of efficiently performing anti-icing or de-icing with a simple structure.[Solving Means] A fan blade 8 is disposed on an air inlet 4 side of a jet engine 1 of an aircraft. The fan blade 8 includes a fan blade main body 21 made of a carbon fiber reinforced plastic (CFRP), and a pair of energizing units 31 and 32 that are provided on a leading edge 24 side and a trailing edge 25 side of a heating region 36 of the fan blade main body 21 and pass current through the fan blade main body 21. Voltage is applied between the pair of energizing units 31 and 32 and current passes through the fan blade main body 21 to heat the fan blade main body 21, thus performing anti-icing or de-icing.
