1. A heat shielding material made of an inorganic material, comprising:
a base material;
a underlayer layered on the base material and having a total solar reflectance (TSR) greater than a TSR of the base material; and
a top layer layered on the underlayer, wherein
the top layer has a thickness such that the underlayer is not visually recognizable, and transmits infrared rays,
the underlayer includes a reaction region between a material of the underlayer and a material of the top layer, and a main reflection region where the material of the top layer is not present, and
the main reflection region has a thickness of 10 μm or more.
