OPTICAL FIBER BLOCK OF OPTICAL MODULE AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide an optical fiber block of an optical module which is devised so that an adhesive may not adhere to the end of an optical fiber and to provide a method of manufacturing the optical fiber block. SOLUTION: An engagement structure body 36 having a second engagement part 38 to be engaged with a first engagement part 31 of a face 11 of a first substrate 1 is formed on the lower face 35 of a second substrate 34 of the optical fiber block in order to make the optical axis of a fiber core part 21 of the second substrate 34 coincident with the core part 17 of the first substrate 1. There are formed a side face positioning structure body (insertion guide groove) 39 for positioning both side faces of the optical fiber 2 and an end positioning structure body (stopper part) 40 which positions by abutting and stopping the end of the optical fiber 2. A third substrate 42 is provided which pinches the optical fiber 2 except the end part thereof between the third substrate 42 and the other face 35 of the second substrate 34 and fixes the optical fiber 2 with an adhesive.
