A cooling block forming a top wall of a combustion chamber of an internal combustion engine is formed by layering, from the outside to the inside, a casing, an upper layer block, a middle layer block, and a lower layer block. Labyrinth-shaped cooling water passages are formed on upper side faces of the three layers of blocks, and cooling water supplied from a cooling water supply passage flows from the cooling water passage on the side far from the combustion chamber to the cooling water passage on the side close to the combustion chamber, and is discharged from a cooling water discharge passage. Since the cooling water flows in a direction opposite to the direction of emission of heat of combustion from the combustion chamber, it is possible to ensure that there is sufficient difference in temperature between a cylinder head and the cooling water throughout the cooling water passages.

In the opto-electronic integrated circuit, an optical waveguide in which a sapphire substrate for an SOS substrate is formed as a lower clad and a silicon film is formed as a core, an electronic integrated circuit formed in the silicon film, and grooves for fixing optical fibers are formed monolithically. Further, a photodiode array and a laser diode array are mounted on a hybrid basis. Since the lower clad of the optical waveguide is used as the sapphire substrate and the core is used as the silicon film, a difference in refractive index can be made large sufficiently, thus resulting in thinning of the silicon film. It is therefore possible to shorten the time required to process the core and the like. Further, since the electronic integrated circuit is formed on the sapphire substrate, the high-frequency characteristics are enhanced.
