To provide a light receiving-emitting device with which it is possible to exhibit more accurate detection functionality.SOLUTION: The light receiving-emitting device comprises: a base material 1; a conductive part 2 which is formed on the base material 1; a first element 3 that is mounted on the base material 1 and emits light; a second element 4 that is mounted on the base material 1 and receives light emitted from the first element 3; a sealing resin 7 that covers the first element 3 and second element 4 and transmits light emitted from the first element 2, the first element 3 and the second element 4 arranged by being spaced from each other in a direction x; a third element 5 that is disposed on the side opposite the second element 4 across the first element 3 in the direction x and receives light from the first element 3; and a light shielding layer 8 which is formed in an uncovered part 73 of the sealing resin 7 that overlaps the third element 5 in a direction z view and composed of a material whose light transmissivity is lower than that of the sealing resin 7.SELECTED DRAWING: Figure 5 【課題】より高精度な検出機能を果たすことが可能な受発光装置を提供すること。【解決手段】基材１、基材１に形成された導電部２と、基材１に搭載され且つ光を発する第１素子３と、基材１に搭載され且つ第１素子３から発せられた光を受光する第２素子４と、第１素子３および第２素子４を覆い且つ第１素子２から発せられた光を透過する封止樹脂７と、を備えており、第１素子３および第２素子４は、ｘ方向において互いに離間して配置されており、ｘ方向において第１素子３を挟んで第２素子４とは反対側に配置され且つ第１素子３からの光を受光する第３素子５と、封止樹脂７のうちｚ方向視において第３素子５に重なる被覆部７３に形成され且つ封止樹脂７よりも光の透過率が低い材質からなる遮光層８と、を備える。【選択図】図５
