An optical module includes a base having a first surface, a board having a second surface and a third surface, an optical circuit element having a fourth surface, a fifth surface and two ports, and an array lens. The first surface is joined to the second surface by a first solder. The third surface has a first metallic pattern and a second metallic pattern that are joined to the fourth surface by a second solder. The array lens is fixed onto the first surface of the base so as to be optically coupled to the two ports provided at one end of the optical circuit element in the first direction. The first metallic pattern is formed closer than the second metallic pattern to the one end of the optical circuit element in the first direction and is formed between the two ports in the second direction.
