[Object] To provide a main rotor blade for a helicopter such as a main blade type helicopter, which may reduce a drag coefficient during high-velocity forward flight and which provides easy control. It is an object of the present invention to provide a helicopter including such a main rotor blade.[Solving Means] A main rotor blade 1, which is the main rotor blade 1 for a high-velocity helicopter, includes: a blade root part 10 having a length of 30% or more of a rotor radius R; and a blade main body 20 continuous with the blade root part 10. Preferably, a cross-sectional shape of the blade root part 10 satisfies (x/a)m+(y/b)m=1 and a>b, where m: arbitrary number, x: chord length direction, and y: blade thickness direction.
