A cutting insert, comprising:

• an upper surface comprising a first corner and a first side extended from the first corner;
• a lower surface located on a side opposite to the upper surface;
• a lateral surface located between the upper surface and the lower surface;
• and
• a cutting edge located on an intersection of the upper surface and the lateral surface, the upper surface further comprising
• a rake surface located along the cutting edge and located closer to the lower surface as going away from the cutting edge,
• a bottom surface located along the rake surface further inwardly than the rake surface, and
• a raised surface located along the bottom surface further inwardly than the bottom surface and located further away from the lower surface as going away from the bottom surface,
• the bottom surface comprising
• a first bottom surface located on a bisector of the first corner in a top view, and
• a second bottom surface located inwardly of the first side, wherein
• the first bottom surface is inclined closer to the lower surface as going away from the first corner, and
