Abstract: Technique to provide a molding die which can easily release a minute optical element in a state of favorable surface accuracy, while bending or rupture of a gate portion attached to the optical element is prevented. By making a first outer circumferential transfer surface 21A of a fixed die 20 and a first gate-forming surface 31A flush with each other, a notch shape is not formed on a portion M1 connecting an outer circumferential portion FL on the fixed die 20 side and a gate portion GP. Furthermore, by pushing out the runner portion RP at the same angle as a taper angle α of a side-surface transfer surface 23A on a second gate-forming surface 32A side, bending deformation or the like of the gate portion GP which can occur when being pushed out to a direction perpendicular to a mold mating surface PL1 can be prevented.

Abstract translation: 技术提供一种成型模具，能够在附着于光学元件的栅极部的弯曲或断裂的同时，以良好的表面精度的状态容易地释放微小的光学元件。 通过使固定模具20的第一外周转印面21A和第一栅极形成面31A相互平齐，在连接固定模具20侧的外周部分FL的部分M1和/ 门部分GP。 此外，通过以与第二浇口形成表面32A侧上的侧表面转移面23A的锥角α相同的角度推出流道部分RP，可以在栅极部分GP的弯曲变形等时发生弯曲变形， 可以防止被推出到与模具配合面PL1垂直的方向。

Abstract: A wide angle optical lens, an optical lens unit, and an imaging device are small-sized and can secure an attachment space even when space is limited, and can avoid adhesion peeling or the extrusion of an adhesive. Optical lens (10) has a lens frame receiving surface (2a) on the side of first optical surface (S1) having a smaller optical surface diameter than second optical surface (S2), and is further provided with an adhesion space forming surface (3a) on the surrounding side of the lens frame receiving surface (2a). Therefore, it is possible to suppress adhesion peeling even when a smaller size is requested. Furthermore, by securing a larger size for lens frame receiving surface (2a), it is possible to suppress leakage or extrusion of adhesive from lens frame receiving surface (2a) and thus adherence to first optical surface (S1).
