| titleOfInvention | Imaging lens unit |
| abstract | This is an imaging lens unit that can be used for solder reflow processes and can be reduced in size and weight. It has heat resistance that can withstand the reflow temperature, and it has optical characteristics for centering the lens and diaphragm even when it is reflowed. Provided is an imaging lens unit that can contribute to miniaturization and high performance by exhibiting excellent optical characteristics in terms of transmittance, refractive index, and the like without loss. An imaging lens unit that includes a lens group including one or a plurality of lenses and a lens barrel that supports the lens group, and is subjected to a solder reflow process, the imaging lens unit comprising an epoxy cation An epoxy cation curable resin lens formed of a curable resin material is essential, and the lens barrel is formed by a thermoplastic resin material having a deflection temperature under load of 200 ° C. or higher, and the epoxy cation cured resin. At least one of the resin lenses has a structure in which a clearance is provided between the lens and the lens barrel, and the lens is supported by lens support portions provided at three or more locations inside the lens barrel. It is. |
