Zusammenfassung:	Before bonding abrasive grain (13) to a core wire (11), a palladium coating (17) is applied to the surface of the abrasive grain (13). The palladium coating (17) is formed as a sea on the surface of the diamond grains (14). In other words, the palladium coating (17) covers the surface of the diamond grains (14) so that the entirety thereof is continuous. Moreover, the palladium coating (17) does not completely cover the diamond grains (14), and a diamond exposed portion (18) is provided by the palladium coating (17) not being applied on a portion thereof. The exposed diamond portion (18) is formed as an island on the surface of the abrasive grain (13). In other words, a plurality of diamond exposed portions (18) are formed as islands separated from each other.
