Abstract
A microlens array, which maintains high positional accuracy with respect to an optical circuit such as a waveguide and facilitates connection operation, and an optical transmission component including the microlens array. Solution The microlens array is provided with a plurality of microlenses arranged in an array structure and having the same length in the optical axis direction and optical fibers for alignment arranged at both ends of the array structure so that the optical axis is parallel to the optical axis of the microlens and having a length in the optical axis direction the same as the length of the microlens and a guided mode diameter smaller than an aperture of the microlens.
