PROBLEM TO BE SOLVED: To provide an optical element module capable of stabilizing the operation temperature of an optical element without being affected by circumferential temperature change, and also rapidly stabilizing the operation temperature of the optical element even when the operation temperature of the optical element is changed. SOLUTION: The optical element module includes: a semiconductor laser 103 for outputting light; a lens 106 for collecting light; an optical fiber 108 to be optically coupled with the semiconductor laser 103 via the lens 106; a case body 101 for storing and fixing the semiconductor laser 103, the lens 106, and the optical fiber 107; a stem 102; and a cap 105. The appearing parts of the case body 101, the stem 102, and the cap 105 are covered with a positive temperature coefficient heater 201 which is formed in a sheet shape and is fixed at prescribed temperature.
