    • A highly miniaturized biosensor and a sensor unit, which can meet a demand for further miniaturization. With this invention, miniaturization is possible, and the number of production steps including those for assembling individual parts can be reduced. Accordingly, mass production will be possible, and cost reduction and high reliability will be achieved. A light emitting unit (21) and a light receiving unit (22) are disposed in a same recess (24) formed on a surface of a semiconductor substrate (23), and a light shielding cover substrate (27) having a first light guide section (25) and a second light guide section (26) is disposed on an upper side of the semiconductor substrate (23). Since the light receiving unit (22) is formed with arrayed light receiving elements (28), the same number of the second light guide sections (26) as the light receiving elements (28) are provided on the light shielding cover substrate (27), and the light receiving surfaces of the light receiving elements (28) are connected to one end of each of the second light guiding sections (26) so as to conform to each other without any gap.
    • 高度小型化的生物传感器和传感器单元,可满足进一步小型化的需求。 利用本发明,可以实现小型化,并且可以减少包括用于组装各个部件的生产步骤的数量。 因此,可以大量生产,并且将实现成本降低和高可靠性。 发光单元(21)和光接收单元(22)设置在形成在半导体衬底(23)的表面上的同一凹部(24)中,并且具有第一导光体 部分(25)和第二导光部分(26)设置在半导体衬底(23)的上侧。 由于光接收单元(22)形成有排列的光接收元件(28),所以在遮光盖基板(27)上设置与光接收元件(28)相同数量的第二导光部(26) ,并且光接收元件(28)的光接收表面连接到每个第二导光部分(26)的一端以便彼此相符而没有任何间隙。
