Abstract
An optical module includes: a first circuit board including a first signal terminal part and a first ground terminal part formed on a front surface; and a second circuit board including a second signal terminal part and a second ground terminal part formed on a back surface. The first circuit board further includes: a first dielectric layer; a first signal wire formed on a front surface of the first dielectric layer; a first ground conductor layer formed on a back surface of the first dielectric layer; and a first through ground conductor passing through the first dielectric layer. The first ground terminal part is formed, in a first region and a second region respectively located on both sides of the first signal terminal part in a first direction, and in a third region prescribed at a location beyond the first signal terminal part in a second direction.
