Claim 0:
1. A laser processing head comprising:
a tubular main body; and
a gas supply part disposed in the main body and allowing an assist gas supplied from outside to flow into an internal space of the main body, wherein the gas supply part includes:
a flow path forming ring, and
two gas supply holes including:
a first gas supply hole extending along a first axis on a plane orthogonal to an axis of a tube of the main body and opening at an inner circumferential surface of the main body; and
a second gas supply hole forming an angle other than 180° relative to the first axis around the axis, extending along a second axis on the plane orthogonal to the axis and opening at the inner circumferential surface;

wherein the flow path forming ring faces the inner circumferential surface with a predetermined interval, and forms a cylindrical space extending along the axis between the flow path forming ring and the inner circumferential surface.
