Abstract

An electronic component includes an electrochemical element, an electrolyte and an outer housing. The electrochemical element includes leading terminals, an anode, a cathode, a separator, and an insulating member. Respective first ends of the leading terminals are connected to the anode and the cathode. The separator is provided between the anode and the cathode. The insulating member is provided in at least one of the separator, the anode and the cathode. The electrochemical element, impregnated with the electrolyte, has a first end face formed by laminating the anode, the separator and the cathode in sequence, and second ends of the leading terminals are led out of the first end face. The outer housing accommodates the electrochemical element and the electrolyte. The insulating member covers the separator in positions corresponding to the first ends of the leading terminals. An end of the insulating member protrudes from the first end face.

Dependent claims

An electronic component comprising:

an electric element constituted by multiple laminated layers including a first electrode foil, a second electrode foil, and a separator interposed between the first and second electrode foils, such that the second electrode foil faces the first electrode foil across the separator;
a first leading terminal having a first end and a second end, the first end of the first leading terminal being connected to a portion of the first electrode foil, the second end of the first leading terminal protruding outwardly from an end of the electric element;
a first insulating member interposed between the second electrode foil and said portion of the first electrode foil;
an electrolyte impregnated in the electric element;
and
an outer housing accommodating the electric element and the electrolyte;
wherein the first insulating member has an end protruding outwardly from said end of the electric element in a same direction that said second end of the first leading terminal protrudes outwardly from said end of the electric element;
and
wherein the end of the first insulating member protrudes by 0.1 mm or more from said end of the electric element and is accommodated in the outer housing.
