Tlae expression for the bootstrap current density due to fusion-produced alpha par-ticles is derived in an axisymmetric plasma by solx'ing a drift kinetic equation in thepresence of both drag and pitch-angle sczxttering. From this expression the alpha-parti-cle induced bootstrap current for a D-1' plasma is explicitly evaluated in a tokamakwith circular cross-section. The evaluated results show that the ratio of this bootstrapcurrent to that due to bulk particles<Joes not become a large value for burningplasmas presently considered. However, the use of this bootstrap current for currentprofile control and a seed current for a steady-state tokamak may be possible.bootstrap current, alpha particle, tokamak, D-T plasma, drift kinetic equation
