Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a thin case and its ultrasonic welding method which does not damage an article contained in the inside and which can be easily welded with ultrasonic wave even when the welding face is thin. SOLUTION: This thin case 100 is constituted of a bottom-side half case body 110 in which energy directors 115 and slits 116 and the like are formed at the welding face of the opening and a cover-side half case body 120 in which receivers 121 to which the energy directors 115 can be fitted and engaging claws 122 are formed. In this ultrasonic welding method, after articles have been contained, both bodies 110, 120 are fitted to each other and ultrasonic wave vibration is applied only on the outer peripheral part of the bottom-side half case body 110 by an ultrasonic horn to weld resin and unify both dobies.
