An optical module of the present invention is provided with a substrate that includes an insulating layer, a passive element provided inside or on the surface of the insulating layer, and terminal electrodes formed on the surface of the insulating layer, and with at least one active element, which includes at least an optical element and is connected to the terminal electrodes on the substrate surface. The passive element has a dielectric layer, a resistive layer, or a magnetic layer, at least one of the terminal electrodes is connected to the passive element, and at least one of the at least one active element has a protruding electrode and is flip-chip mounted to the terminal electrodes on a principle face of the substrate via the protruding electrode. Taking a plane parallel to the principle face of the substrate as a projection plane, then an area of orthographic projection of the dielectric layer, the resistive layer, or the magnetic layer is smaller than an area of orthographic projection of the principle face of the substrate, and the dielectric layer, the resistive layer, or the magnetic layer is formed such that the orthographic projection, with respect to the projection plane, of all the protruding electrodes of the at least one active element that is flip-chip mounted to the principle face of the substrate is included in the orthographic projection of the dielectric layer, the resistive layer, or the magnetic layer. Thus, the optical module has good high frequency properties and the optical element can be mounted stably onto the substrate.
