PROBLEM TO BE SOLVED: To enhance cooling efficiency in a cooling device and an electronic apparatus using the cooling device.SOLUTION: A cooling device includes: a plurality of heat receiving sections 8 abutting on a plurality of heat generating bodies 6; a heat radiation path 12 connected to the heat receiving sections 8 via connecting sections 15; a heat radiating section 9 connected to the heat radiation path 12 via a heat radiation inflow port 14; a return path 13 for connecting the heat radiating section 9 and the heat receiving sections 8; and check valves 23 connected to the heat receiving sections 8. A path from the return path 13 via the check valves 23, the heat receiving sections 8 and the heat radiation path 12 to the heat radiating section 9 is formed. A cross sectional area in the heat radiation path 12 is sufficiently larger than a cross sectional area in the connecting section 15, and each of the plurality of connecting sections 15 is connected to the heat radiation path 12.SELECTED DRAWING: Figure 2
