<P>PROBLEM TO BE SOLVED: To provide a light transmission/reception module and an electronic unit, which can obtain a high S/N. <P>SOLUTION: The light transmission/reception module has a light emitting element emitting transmission signal light and a light receiving element receiving reception signal light, and it transmits transmission signal light and receives reception signal light by sharing an optical fiber of one core. A light emitting device 91 is covered so that it is sandwiched by an upper shielding plate 93 and a lower shielding plate 94 by using conductive metal plates. Connection terminals 95 and 96 of the upper shielding plate 93 and the lower shielding plate 94, which extend in the pull-out direction of the lead terminal 99 of the light emitting device 91, are connected to a ground terminal of a lead terminal 99. <P>COPYRIGHT: (C)2003,JPO |
