PROBLEM TO BE SOLVED: To provide a reliable and excellent optical module that not only the breakage of an optical fiber and the breakage of sealing structure are prevented as much as possible but also optical connection between the optical fiber and an optical element is precisely executed. SOLUTION: The optical module M houses a V-groove substrate 5 mounting the optical element 18, the optical fiber 7, etc., to be optically connected with this. A good heat conductor pattern 6 precisely positioned to the center axis of a V groove 12 and connected with the element 18 is formed 7 on the lower surface of the substrate 5, a through hole 9 for putting the fiber 7 through is provided on the side part of the housing 1 through which the center axis of the V groove 12 passes, connection pads 3a, 3b,... positioned to the center of the hole 9 are provided on the bottom surface of the housing 1 to connect the lower surface of the substrate 5 and the pads 3a, 3b,..., and the fiber 7 and the hole 9 with soldering 4a, 4b,....
