Optical module

An optical module, comprising:

• a light emitter configured to emit a light;
• a light receiver configured to receive the light emitted from the light emitter;
• a first lens and a second lens, which are provided between the light emitter and the light receiver, and which are aligned in an optical axis direction of the light emitted from the light emitting unit;
• and
• a base member on which the light emitter and the light receiver are placed, and each of the first lens and the second lens is fixed via a layer of adhesive resin having a predetermined thickness,
• wherein the first lens has a first bonding surface, and the first bonding surface being an only portion of the first lens bonded to the base member via the layer of adhesive resin so that the first lens is fixed to the base member,
• wherein the second lens has a second bonding surface, and the second bonding surface being an only portion of the second lens bonded to the base member via the layer of adhesive resin so that the second lens is fixed to the base member,
• wherein a first bonding direction being a stacking direction of the first bonding surface of the first lens and the layer of adhesive resin, and a second bonding direction being a stacking direction of the second bonding surface of the second lens and the layer of adhesive resin are respectively perpendicular to the optical axis direction of the light, and
• wherein an orientation of the first bonding surface and an orientation of the second bonding surface are different from each other.
