PROBLEM TO BE SOLVED: To provide a method for producing a heat radiation plate, in which the cost of a tool can be reduced, convenience in working is improved, metal powder is uniformly laid and the metal powder is effectively prevented from being moved by the movement of a heat radiation piece. SOLUTION: The method for producing the heat radiation plate includes the steps of: arranging heat radiation pieces 2 on the lower tool 11 of powder packing equipment 1; combining the upper tool 12 and the lower tool 11 of the powder packing equipment 1 tightly with each other; causing the upper tool 12 to join a stretching spacing component 121 closely to the heat radiation pieces 2; packing the metal powder 3 onto the heat radiation pieces 2 from the powder introduction port 122 of the upper tool 12 by a positive pressure method; vibrating the heat radiation pieces 2 to apply the metal powder 3 uniformly on the heat radiation pieces 2; taking out the upper tool 12; jetting an organic liquid 4 toward the metal powder 3 packed on the heat radiation pieces 2; forming the metal powder 3 in a fixed shape on the heat radiation pieces 2; and finally removing the heat radiation pieces 2 from the lower tool 11 and sintering the removed heat radiation pieces.
