PROBLEM TO BE SOLVED: To provide optical parts which have a small coupling loss, a long life, and a high reliability by reducing a gap generated between an end face of an optical fiber block and an end face of an optical element block as much as possible and to provide a method of manufacturing the same. SOLUTION: Optical parts 10 are constituted of an optical fiber block 12 and an optical element block 14. The optical fiber block 12 is constituted of a substrate 16, V grooves 18 formed in the substrate 16, an optical fiber array 22 of optical fibers 20 stored in the V grooves 18 respectively, and a retaining member 24 for holding the optical fiber array 22 together with the substrate 16. The optical element block 14 is constituted of a substrate 30, a ceramic substrate 32 formed on the substrate 30, and an optical element array 36 of optical elements 34 formed on the ceramic substrate 32. The substrate 16 and the substrate 30 are stuck at spot welding points 42 formed by YAG laser. COPYRIGHT: (C)2004,JPO
