摘要： PROBLEM TO BE SOLVED: To provide an optical element module which has small variations in light loss against wide-range temperature variations. SOLUTION: This optical element module 1 is equipped with a housing, an optical element installed in the housing, and a pipe linking outer and inner sides of the housing, and constituted so that a primary coated optical fiber is inserted into a pipe and connected to the optical element. Consequently, the problems that, conventionally in optical element module, since a primary coated optical fiber 21 and a housing of the optical element module shrink as ambient temperature becomes low, expansion/contraction stress has been generated between two points of an optical fiber holding part for bonding and fixing the primary coated optical fiber for light input and an adhesive fixation part fixed to the housing with an adhesive, and consequently, the primary coated optical fiber for light input has a microbend to cause an increase in light loss, is solved.
