<P>PROBLEM TO BE SOLVED: To provide: a sintered compact sheet for an electrolytic capacitor electrode which allows the enhancement of elasticity of the sintered compact while solving the problems in connection with sintering distortion that a laminate with a sintered valve metal powder compact for an electrode provided on a surface of a supporting foil is prone to sintering distortion between the foil and the powder, resulting in the warp of the laminate or causing a crack or peeling in a portion of the sintered powder compact, and that a sheet formed by the sintered compact without the supporting foil is prone to be fragile; and a method for manufacturing the sintered compact sheet. <P>SOLUTION: The valve metal powder includes polyimide powder. The manufacturing method comprises the steps of: mixing the valve metal powder, the polyimide powder and the like to form particles; temporarily shaping the particles; defatting the particles; exhausting the inside of a vacuum chamber 8, followed by pressing; and then performing the discharge plasma sintering by a power supply unit 5 with electrodes 3 and 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
