PROBLEM TO BE SOLVED: To obtain a ball lens fixing structure that enables an optical fiber and a ball lens to be aligned more easily and more accurately. SOLUTION: Two substrates 2, 3 are joined in a manner that the grooves (2b, 3b) provided in each joining face 2a, 3a of the two substrates 2, 3 are faced with each other to form a cavity 4. Between the oppositely facing wall faces 4d of the cavity 4, a spring 9 is installed in one wall face while, in the other wall face, a through hole 14 is formed in which a pin 15 is inserted projectingly to the cavity 4 side. A ball lens 6 is held between the spring 9 and the pin 15. COPYRIGHT: (C)2006,JPO&NCIPI
