Abstract: A multilayer wiring substrate according to the present invention includes a dielectric base body, a signal line in or on the dielectric base body, a ground conductor in the dielectric base body, and a graphite sheet in the dielectric base body. The dielectric base body is a laminate including dielectric sheets stacked on top of each other. The ground conductor and the signal line face each other in a stacking direction of the dielectric sheets. The ground conductor overlaps the signal line when viewed in plan in the stacking direction. The graphite sheet and the signal line face each other in the stacking direction without the signal line being located between the graphite sheet and the ground conductor. An upper surface of the graphite sheet is coplanar with an upper surface of the ground conductor or is located below the upper surface of the ground conductor.

Abstract: A cooling module includes an electroosmotic pump. The electroosmotic pump includes a first electrode which is permeable to a cooling fluid, a second electrode which is located with an interval from the first electrode and is permeable to the fluid, and a dielectric layer which is located between the first electrode and the second electrode and includes a microchannel which is permeable to the fluid. The first electrode and the second electrode have different polarities.
