An optical module includes: a first substrate with a first surface, the first substrate having some first pads on the first surface; a second substrate with a second surface, the second substrate having some second pads on the second surface, each of the first pads and a corresponding one of the second pads being opposed to each other and constituting an opposed pair of pads; a first insulation wall between an adjacent pair of the first pads, and in contact with the first surface of the first substrate; and a second insulation wall between an adjacent pair of the second pads, and in contact with the second surface of the second substrate. The first insulation wall and the second insulation wall overlap with none of the opposed pair of pads and are adjacent to each other in a direction along the first surface and the second surface.
