Abstract
The present invention has as its object the provision of a lithium ion capacitor having high capacity and high output characteristics and also having high safety that allows suppression of an increase in surface temperature even when an internal short circuit accidentally occurs. The lithium ion capacitor of the present invention comprises: a lithium ion capacitor element formed by overlaying a positive electrode sheet and a negative electrode sheet on top of one another with a separator interposed therebetween; an electrolyte solution; and an outer container that contains the lithium ion capacitor element and the electrolyte solution, a porous layer is formed on an outer surface of the lithium ion capacitor element, and the lithium ion capacitor satisfies following relational expressions (1) and (2):35≦  relational expression (1):0.01≦≦5  relational expression (2):
