PROBLEM TO BE SOLVED: To provide a heat insulating material that is obtained by forming aerogel particles containing fabric with a plurality of salient portions, and has high strength and superior heat insulating properties.SOLUTION: A heat insulating material is formed by containing aerogel particles A, and fabric 1 having salient portions 2 bonding to the aerogel particles A. The length of the salient portion is shorter than an average particle size of aerogel particles, and narrower in thickness than an average pore size of aerogel particles. An interval between the salient portions is broader than the average pore size of aerogel particles and narrower than the average particle size of aerogel particles. |
