An electrolytic capacitor module includes a plurality of capacitor elements, an electrode lead, a sealing member, and a heat dissipation member. The electrode lead is electrically connected to each of the plurality of capacitor elements, and penetrates through the sealing member. The heat dissipation member has a plurality of housing portions that respectively house the plurality of capacitor elements. Further, the heat dissipation member has a first surface and a second surface opposite to the first surface. Each of the plurality of housing portions has an insertion opening opened in the first surface. The sealing member seals the insertion opening. The electrode lead is led out from the insertion opening.

Disclosed is an electrode leading-out method and packaging method for a tantalum electrolytic capacitor. The electrode leading-out method includes the following steps: S1, fabricating an insulating protective layer outside an electrode body of the tantalum electrolytic capacitor; S2, exposing a cathode leading-out part on a cathode pre-leading-out part, and exposing a tantalum core leading-out end in an area where a terminal of a tantalum core is located; S3, depositing a metal layer on each of the cathode leading-out part and the tantalum core leading-out end which are exposed; and S4, fabricating an outer electrode for mounting on each of the metal layer of the cathode leading-out part and the metal layer of the tantalum core leading-out end so as to respectively lead out a cathode and an anode.
