An optical transmitting and receiving device 1 includes a main body portion 4 and has a base substrate 5 at a bottom-surface side of this main body 4. In a front surface 5a of this base substrate 5, formed is a recess-like first cavity 7 and second cavity 8, and an LD 9 is disposed in the first cavity 7, and a PD 12 is disposed in the second cavity 8. An LD terminal electrode 15 of the LD 9 is electrically connected, via a wire 28, to a base substrate wiring portion 19 formed on an insulating film 40 on the front surface 5a. Moreover, in a light shielding member 20 laminated on and fixed to the front surface 5a side of the base substrate 5, formed is a wire storing portion 29 to store the wire 28. Since these make it no longer necessary to provide a space to store the wire 28 in the first cavity 7, it becomes possible to downsize the first cavity 7. Accordingly, it becomes possible not only to downsize the base substrate 5 but also to downsize the optical transmitting and receiving device 1. |
