Abstract
[Objective] To restrict degradation of optical characteristics due to a resin adhesive containing an inorganic filler. [Means] The width d of a lens bodyand the height of an inorganic fillerin a direction orthogonal to the surface of a substrate are set such that an inclination angle of a collimating lensdoes not exceed a maximum tolerable inclination angle when the inorganic filleris positioned near the width-wise center of the lens body. As a result, even when the inorganic filleris inserted between the bottom surface of the collimating lensand the top surface of the substrate, degradation of the optical characteristics of the laser module including skewing of the optical axis of the laser light and distortion of the beam shape of the laser light can be restricted.
