Abstract: Provided are a rare earth permanent magnet whose permanent magnetic properties are improved by making density of the magnet very high and a method for manufacturing a rare earth permanent magnet. Thus, magnet raw material is milled into magnet powder, and then a compound is formed by mixing the magnet powder thus milled with a binder. Next, the compound thus formed is subjected to hot-melt molding onto a supporting substrate so as to form a green sheet molded to a sheet-like shape. Thereafter, while the green sheet thus molded is softened by heating, magnetic field orientation is carried out by applying a magnetic field to the green sheet thus heated; and further, the green sheet having been subjected to the magnetic field orientation is calcined in non-oxidizing atmosphere, and then, sintering thereof is carried out at a sintering temperature to produce a permanent magnet having density of 95% or more.
