A capacitor comprising: a capacitor element having electrode foils (18, 20) on the anode side and the cathode side laminated via separators, connecting parts (22A, 22B) of terminal components (8A, 8B) being disposed inside a laminated portion of the electrode foils and the separators, the connecting parts being connected to the electrode foils on the anode side and the cathode side respectively; and a case that includes a storage part storing the capacitor element and having an opening portion sealed by a sealing body, that has crimped parts (12B, 12C) crimped from the outside of the storage part toward a side surface of the capacitor element, and that holds the capacitor element with the crimped parts, wherein the terminal components include the connecting parts on one end side, and a length of the connecting parts is shorter than a length of the capacitor element, the case is crimped to form the crimped parts while avoiding a position at which the electrode foils of the capacitor element in the storage part overlap with tip portions of the connecting parts of the terminal components, the crimped parts are formed at least at two positions different in height for the side surface of the capacitor element in the storage part, and include a first crimped part crimping a position at which the electrode foils overlap with the connecting parts of the terminal components and a second crimped part crimping the side surface of the capacitor element at a position at which the electrode foils do not overlap with the connecting parts, and a crimping amount on the case is differentiated between the first crimped part and the second crimped part depending on a difference in element diameter of the capacitor element. a capacitor element having electrode foils (18, 20) on the anode side and the cathode side laminated via separators, connecting parts (22A, 22B) of terminal components (8A, 8B) being disposed inside a laminated portion of the electrode foils and the separators, the connecting parts being connected to the electrode foils on the anode side and the cathode side respectively; and a case that includes a storage part storing the capacitor element and having an opening portion sealed by a sealing body, that has crimped parts (12B, 12C) crimped from the outside of the storage part toward a side surface of the capacitor element, and that holds the capacitor element with the crimped parts, wherein the terminal components include the connecting parts on one end side, and a length of the connecting parts is shorter than a length of the capacitor element, the case is crimped to form the crimped parts while avoiding a position at which the electrode foils of the capacitor element in the storage part overlap with tip portions of the connecting parts of the terminal components, the crimped parts are formed at least at two positions different in height for the side surface of the capacitor element in the storage part, and include a first crimped part crimping a position at which the electrode foils overlap with the connecting parts of the terminal components and a second crimped part crimping the side surface of the capacitor element at a position at which the electrode foils do not overlap with the connecting parts, and a crimping amount on the case is differentiated between the first crimped part and the second crimped part depending on a difference in element diameter of the capacitor element.
