Abstract
An optical element comprising a transparent bodyincluding a first end facea second end faceforming a prescribed angle to the first end face; and a third end facehaving a plurality of light reflection partsformed on, which respectively reflect a plurality of light signals entering one of the first end face and the second end face to cause to exit at the other of the first end face and the second end face, a pitch of the plurality of light reflecting parts formed on the third end face, which are projected on the first end face being a first pitch, and a pitch of the plurality of light reflecting parts formed on the third end face, which are projected on the second end face being a second pitch which is different from the first pitch. The light emitting element array, etc. including the light emitting elements, etc. arranged at the first pitch in an array, and the optical waveguide array including the optical waveguides arranged at the second pitch in an array can be easily connected optically with each other.
