PURPOSE:To obtain the small-sized photodection module with high performance which can have its optical axes easily adjusted. CONSTITUTION:The small-sized photodetection module 1 consists of at least >=1 optical fiber 4, an optical fiber holding member 2 where grooves 5 having a fiber fixing function and an optical path converting function are formed, and a photodetecting element formation member 3, and is constituted by precisely arranging and sticking the photodetecting element formation member 3 which has position relation adjusted so that the projection light from the optical fibers 4 is made efficiently incident on the phtodetection part of a photodetecting element 7 after the optical paths are converted by a machined surface 6 with a reflecting function which is provided on the member. |
