PROBLEM TO BE SOLVED: To provide an ice/snow accretion preventive material which facilitates work such as dimensional adjustment in the construction field, facilitates mounting thereof in an angle steel member of a steel tower, does not mar the appearance, positively prevents ice/snow accretion in an inner space of the angle steel member, and is excellent in durability. SOLUTION: The ice/snow accretion preventive material 1 is made of a synthetic resin foam molded body which can cover the inner space 53 of the angle steel member 50 forming the steel tower. The ice/snow accretion preventive material includes engaging portions 11, 12 for fitting to and engaging with edges 51a, 52a of respective side plates 51, 52, at both side edges of a cover plate 10 covering the inner space 53, in a longitudinal direction. Thus, by using the engaging structure, the ice/snow accretion preventive material can be easily mounted on the angle steel 50, to thereby cover the inner space 53 like a cover.
