To provide a V-type internal combustion engine capable of forming a breather path having a sufficiently large flow path area without enlarging a cylinder block. A 5-cylinder V-type internal combustion engine includes a breather apparatus, a crankshaft having three crankpins and a cylinder block formed with a front bank of three cylinders and a rear bank of two cylinders. Two crankpins disposed at both ends are connected with two connecting rods connected to pistons fitted to cylinder bores formed in the front and the rear banks. A crankpin disposed in the middle is connected only with a connecting rod connected to a piston fitted to a cylinder bore formed at a middle of the front bank and in the rear bank. A breather path of a breather apparatus is formed at a space portion between the two cylinder bores at a position opposed to the cylinder bore in the middle.
