A cooling apparatus includes: a heat receiving portion including a heat receiving plate which transfers heat from a heat source to a working fluid; a heat radiating portion which discharges the heat of the working fluid; and a heat radiating path and a return path which connect the heat receiving portion and the heat radiating portion to each other. In the cooling apparatus, the working fluid is circulated through the heat receiving portion, the heat radiating path, the heat radiating portion, the return path and the heat receiving portion to dissipate the heat of the heat source. A check valve which controls a flow of the working fluid is provided in the return path at a location near the heat receiving portion or provided in the heat receiving portion. The check valve includes a valve seat including a valve hole, a case including a recess, and a valve plate which is sandwiched between the valve seat and the case, which opens and closes the valve hole, and which includes a valve-movable portion that moves in the recess. |
