[Object] To provide a sensor module and a method for producing the sensor module, the sensor module making it possible to improve a degree of freedom in design, to facilitate the operation, and to reduce costs by reducing the number of components. [Solving Means] A sensor module according to an embodiment of the present technology includes a first member, a second member, a third member, and a sensor element. The first member is made of a synthetic resin material that has absorptive properties with respect to first laser light. The second member is made of a synthetic resin material that has transmissive properties with respect to second laser light of a wavelength that is different from a wavelength of the first laser light. The third member is made of a synthetic resin material that has transmissive properties with respect to the first laser light and has absorptive properties with respect to the second laser light, the third member including a first surface and a second surface, the first surface including a first welding portion that is welded to the first member, the second surface including a second welding portion that is welded to the second member.

A fluidic device including an inorganic solid support attached to an organic solid support by a bonding layer, wherein the inorganic solid support has a rigid structure and wherein the bonding layer includes a material that absorbs radiation at a wavelength that is transmitted by the inorganic solid support or the organic solid support; and a channel formed by the inorganic solid support and the organic solid support, wherein the bonding layer that attaches the inorganic solid support to the organic solid support provides a seal against liquid flow. Methods for making fluidic devices, such as this, are also provided.
