Abstract
An abrasive wire provides an efficient cutting operation with high accuracy and a longer service life. Abrasive grains are provided around a core wire. The abrasive grains are bonded to the core wire by a light curing resin or an electron beam curing resin which can be cured within a few seconds. Accordingly, the curing operation can be performed while the core wire is moved in the direction of the longitudinal axis of the core wire. Thus, a long abrasive wire can be fabricated at reduced time and cost.

- a core wire;
- abrasive grains provided around the core wire;
- and
- a bonding layer including a plurality of layers each of which is made of a light curing resin, each of the plurality of layers being made of a different kind of light curing resin.
