PROBLEM TO BE SOLVED: To provide a mounting substrate on which each chip is fixed on a predetermined position of the substrate at high positional accuracy. SOLUTION: Each solder wettable pattern 21a of a planar shape obtained by radially protruding protrusions from a center of the mounting substrate 1 is formed on the mounting substrate 1, a solder pattern 23a having substantially the same planar shape as the solder wettable pattern is selectively formed on the solder wettable pattern and the solder pattern is depressed to flatten the surface of the solder pattern.

PROBLEM TO BE SOLVED: To provide a composite photoelectric device capable of enhancing the relative positioning precision between an interposer and an optical waveguide with respect to an optical coupling method based on an IC socket. SOLUTION: The interposers 106a and 106b, on the back surfaces of which optical elements (a light emitting element array 107 and a light receiving element array 108) are mounted, are fixed on protruded surfaces of the IC sockets 102a and 102b mounted on a substrate 101. The end parts of an optical waveguide array 103 are disposed on grooved recesses 102d of the IC sockets 102a, 102b so as to face the optical elements. The positioning of the interposers and the optical waveguide array is performed by inserting positioning pins 111 of the interposer into positioning holes 112 of the the optical waveguide array 103. The interposer and the optical waveguide array are directly connected by the positioning pins. Accordingly, the relative positioning precision between the interposer and the optical waveguide array can be enhanced. COPYRIGHT: (C)2006,JPO&NCIPI
