PROBLEM TO BE SOLVED: To provide a thermosetting resin molding material which can be molded into an article with any shape and size with remarkably decreased burrs formerly impossible. SOLUTION: This molding material mainly comprises a thermosetting resin and a filler, provided that the filler is composed so that the value (F<SB>L</SB>) obtained by multiplying three items: the inverse number of the undersize integrate volume percentage 10% equivalent diameter (X<SB>10</SB>), the accumulation frequency f(t) of particles with an equivalent diameter larger than the air vent thickness, and the filling ratio (1-ε), is 5 or more. The molding material can be applied to an air vent with any thickness. COPYRIGHT: (C)2004,JPO
