PROBLEM TO BE SOLVED: To improve environmental stability of electrical connection between a substrate and a terminal in a battery with the terminal having a compliant pin portion pressed and fitted into a through-hole of the substrate. SOLUTION: In the battery in which the terminals 2, 3 having the compliant pin portions 2a, 3a are connected to a battery container into which a power generating element and an electrolytic solution are sealed, as the terminal, at least a metal portion of the same kind as a conductive material to form the through-hole is installed at a portion contacting the conductive material to form the through-hole of a circuit board mounting this battery, and an R face or a C face are installed at a corner of the metal portion.
