Claim 0:
1. A turbine vane comprising:
an airfoil having a leading edge and a trailing edge;
an inner shroud disposed at one end of the airfoil to support the airfoil; and
an outer shroud disposed opposite to the inner shroud at the other end of the airfoil to support the airfoil,
wherein a corner part is formed at a portion where the airfoil and the inner shroud or the outer shroud meet, the corner part comprising:
a first round portion connected in an arc shape to the inner shroud or the outer shroud;
a first inclined portion connected to the first round portion and outwardly extending in an inclined shape, a longitudinal section of the first inclined portion being formed in a straight line; and
a second round portion connected to the first inclined portion and outwardly extending in an arc shape,
wherein a first curve from a radially outer end and a radially inner end of the first round portion is formed in a first concave curve, having a first central point of the first curve located outside the turbine vane,
wherein a second curve from a radially outer end and a radially inner end of the second round portion is formed in a second concave curve, having a second central point of the second curve located outside the turbine vane.
