The The lens diameter of the first lens 20 is, for example, not less than 0.1 mm and not more than 0.5 mm.

  The first lens 20 can be made of, for example, a transparent resin material such as a polyetherimide resin, an epoxy resin, a polyimide resin, a phenol resin or an acrylic resin, or a glass material. The first lens 20 may be manufactured using a material different from that of the substrate 10 or may be manufactured using the same resin material as that of the substrate 10. When the substrate 10 and the first lens 20 are manufactured using the same resin material, the thermal expansion coefficient of the substrate 10 and the thermal expansion coefficient of the first lens 20 can be made equal.

As a result, a large area of the end surface 51 can be secured, and the optical component 1 and the ferrule can be stably connected.

  For example, as shown in FIG. 4, the protrusions 50 may be disposed at both ends in the longitudinal direction (Y-axis direction) of the side surface 11 b. As a result, the optical component 1 and the ferrule can be stably connected.

The surface is a facing surface 61c. In addition, the overhang | projection part 64 may contact | abut two surfaces which a pair of protrusion part 50 mutually opposes, As a result, the optical component 1 and the ferrule 60 can be connected stably.
