A cutting insert may include a base member and a coating layer thereon. The coating layer may include a first layer including a titanium compound on the base member, a second layer including alumina and an upper surface on the first layer, and a third layer including a titanium compound on the upper surface. The coating layer may include a crack at a top surface and therein. In a cross section orthogonal to the top surface, the crack may be present in the third layer and the second layer; in the third layer it may have a width of 1 μm or more. In the upper surface it may have a width of 0.5 μm or more—smaller than the width of the crack in the third layer. Another part may have a width of 0.2 μm or less closer to the base member than the upper surface.
