PROBLEM TO BE SOLVED: To improve the stability of a coolant and to obtain an excellent cooling effect. SOLUTION: In this base 10 for the coolant, the coolant 20 is placed on a base main body 12, covered with covers 14 and 16 and fixed. By leg parts 26 and 28, a projection part 34 is selectively inserted to the rectangular hole 12A of the base main body 12 and a supporting height is adjusted. Since the base main body 12 is deflected by the weight of a human body head part, a contact area with the head part is increased, thereby the cooling effect is increased.
