PROBLEM TO BE SOLVED: To provide a surface mount electrolytic capacitor for improving adhesion between an external resin case and an encapsulating case cover and hard to cause a change in characteristics, and to provide its manufacturing method. SOLUTION: The surface mount electrolytic capacitor has, as the encapsulating case, a box-shaped resin case 2 with its upper opened having a positive electrode terminal 6 and a negative electrode terminal 7 incorporated in its bottom and the encapsulating case cover 1 for covering external surfaces of upper and sidewalls of the case 2. A protrusion 1a is formed on an internal ceiling surface of the encapsulating case cover 1, and thus a dent 1b is formed between an inner sidewall surface of the cover 1 and the protrusion 1a. The dent 1b and a sidewall upper end of the resin case 2 are fitted with each other via an adhesive 3. In addition, the protrusion 1a on the internal ceiling surface of the cover 1 holds the upper surface of a capacitor element 8, thereby preventing it from shifting in position.
