PROBLEM TO BE SOLVED: To provide a lightweight impact resistant member with high impact resistance, capable of reducing impact to a protection object. SOLUTION: The impact resistant member 10 is used in protection with respect to the impact of a high speed flying object, and it includes a base 11 formed of a metal based composite material or ceramics comprising a base material of reinforcement of ceramics and metal, and impact absorbers 12, 13 joined to the base 11 and formed by including high strength fiber. The base 11 has a density of 3.5×10<SP>3</SP>kg/m<SP>3</SP>or less, and a Rockwell strength HP larger than 55 when echo tip rigidity measurement is carried out. Thus, the impact resistant member is light in weight and excellent in impact resistance. Accordingly, the impact resistant member 10 can suppress deformation and can be applied to a lightweight product capable of reducing impact to a protection object. And, since the base 11 is formed of a metal based composite material or ceramics, impregnation of a metal base material or processing before burning of ceramics becomes easier.
