Abstract

The laser module includes a QCL element, a MEMS diffraction grating, a first lens holder disposed on a side opposite to a side on which the MEMS diffraction grating is disposed with respect to the QCL element, a second lens holder disposed between the QCL element and the MEMS diffraction grating, a package, an electrode terminal disposed along an inner wall surface of the package, and a wire for electrically connecting the electrode terminal and the QCL element. An end portion of the wire is disposed on a side where the QCL element is disposed, the end of the wire is disposed at a position between the first lens holder and the second lens holder when viewed from a direction orthogonal to a facing direction in which the first lens holder and the second lens holder face each other.
