CAPACITOR ELECTRODE BODY, METHOD FOR MANUFACTURING CAPACITOR ELECTRODE BODY, CAPACITOR, AND METHOD FOR MANUFACTURING CAPACITOR

摘要

An anode body (2) comprises: an anode substrate (4) made of at least one of a valve action metal and an alloy thereof; and a porous layer (6) provided on the anode substrate (4) and formed by bonding a plurality of secondary particles (8) of a first metal particle (7) made of at least one of the valve action metal and the alloy thereof. The porous layer (6) includes: a scattering region (X) formed inside the secondary particles (8); and a dense region (Y) having a void rate lower than that in the scattering region (X) and formed between the anode substrate (4) and the secondary particles (8) and between the secondary particles (8).
