A prismatic secondary battery includes an electrode body including a positive-electrode sheet and a negative-electrode sheet, a prismatic exterior body that accommodates the electrode body, a sealing plate that seals an opening of the prismatic exterior body, and a negative terminal electrically connected to the negative-electrode sheet. The prismatic secondary battery is arranged such that the sealing plate extends in the vertical direction during use of the prismatic secondary battery. The positive-electrode sheet is electrically connected to the sealing plate. The sealing plate has a recessed portion on an outer surface and a terminal insertion hole formed in the recessed portion. The negative terminal is inserted in the terminal insertion hole. An outer insulating member is disposed between the negative terminal and the sealing plate. The sealing plate has a first groove extending to an end of the recessed portion in the longitudinal direction of the sealing plate.
