To provide a metal bond wheel having a more excellent electric discharge truing characteristic and a grinding characteristic, in a grinding method utilizing electric discharge truing technique.

The metal bond wheel uses the bond where the thermal conductivity is 2 W/(mK) or more and 100 W/(mK) or less, the melting point is 400C or more and 800C or less, and a 50 wt.% or more intermetallic compound is included in the metal bond. The metal bond is bronze based metal bond and the one where Sn content is 20 wt.% or more and 50 wt.% or less is preferable. it is preferable that the metal bond contains 20 wt.% or less of 10 m or more and 100 m or less graphite particles.
