Abstract

PROBLEM TO BE SOLVED: To prevent the possibility that a crack is developed at an end of a luminescent container at the time of forming the luminescent container or during a thermal cycle. SOLUTION: This luminescent container 1 is equipped with a body 4 having a tubular body part 2 and a cap part 3 that is integrated at one end of the body part 2 and has a hole, and a cap 5 fitted into the other end of the body part 2. A tapered part 6 is formed at an end, on the side on which the cap part 3 is formed, of the internal space formed from the inside walls of the body part 2 and the cap part 3. Because thermal stress generated during a thermal cycle is dispersed without being concentrated at the one end X by forming the tapered part 6, a crack is hardly developed at the end X during the thermal cycle. In addition, when the tapered part 6 like that is formed, the end X can uniformly be compressed easily at the time of forming the luminescent container, so that a crack is barely developed at the one end X of the formed body of the luminescent container 1.
