Abstract: Provided are a heat pipe coolant capable of suppressing deformation of a flat plate-like heat pipe, and a flat plate-like heat pipe. The heat pipe coolant is a coolant enclosed in a flat plate-like heat pipe serving as a heat diffusion plate. The heat pipe coolant includes water and a deformation suppressant that lowers the hardness when the water freezes. The deformation suppressant is 1,4-dioxane or diethylene glycol dimethyl ether. A content of the water is 90 wt % or greater. A content of the deformation suppressant is 0.5 wt % or greater.
