Capacitor

A capacitor comprising:

• a capacitor element including an element body and an external electrode on an end surface of the element body;
• a lead-out terminal electrically connected to the external electrode;
• an outer case housing the capacitor element inside so that the lead-out terminal projects outward, the outer case having:
• a bottomed tubular shape with an opening part at a first end thereof,
• a bottom wall sealing a second end while facing the opening part,
• a side wall projecting toward the opening part from the bottom wall,
• a guide groove constructed to regulate a position of the lead-out terminal on an inner surface of the outer case, the guide groove protruding from the side wall and extending between the opening part and the bottom wall, wherein
• a height of the guide groove proximal to the opening part of the outer case is lower than a height of the side wall proximal to the opening part of the outer case;
• and
• a filling resin filling a space between the capacitor element and the outer case.
