Abstract: The imaging-device lens module includes a lens and a spacer. The lens includes a functioning portion, a non-functioning portion, and a support. The non-functioning portion is disposed around the periphery of, and is integral with, the functioning portion. The support is integral with the non-the functioning portion and supports the lens. The spacer has a flat top face, and the support has a flat bottom face. The spacer is bonded at the top face to the bottom face to support the lens. The top face has a width B, and the bottom face has a width A, where B is greater than A. The support has a height L1, the spacer has a height L2, and the functioning portion has a diameter D, where the total of L1 and L2 is greater than D, and where the diameter D is equal to or greater than the height L1.

Abstract: As a first aspect, provided is a hybrid lens for which peeling and shifting of a glass and a resin lens do not easily occur, and for which floating of an adhesive layer and peeling between the glass and resin lens do not easily occur even when the hybrid lens is exposed to a high temperature environment. As a second aspect, provided is an easily produced hybrid lens in which a glass and a resin lens are laminated, and in which the resin lens and a light-shielding portion are laminated with good precision.
The hybrid lenses 11 and 12 each include a glass substrate 3, a resin lens 2, and an adhesive layer 4 provided between the glass substrate 3 and the resin lens 2. In the hybrid lens 11, the glass transition temperature of the resin lens 2 is higher than the glass transition temperature of the adhesive layer 4, and the difference between the glass transition temperature of the resin lens 2 and the glass transition temperature of the adhesive layer 4 is from 97 to 150° C. The hybrid lens 12 further includes a metal compound layer 52 provided between the glass substrate 3 and the resin lens 2.
