摘要：
PROBLEM TO BE SOLVED: To improve reliability of a solar battery module.SOLUTION: Inside a case 2 constituting a solar battery module 1, a string which is configured by electrically connecting a plurality of solar battery cells 3a by wiring 3b is arranged. The string is covered with a sealing body 4 packed inside the case 2. The sealing body 4 is provided with a space 5. The space 5 is a portion for relaxing a stress applied to the solar battery cell 3a and the wiring 3b from the sealing body 4 because of thermal expansion of the sealing body 4, by absorbing the thermal expansion of the sealing body 4. Thus, a failure such as cracking of the solar battery cell 3a, disconnection of the wiring 3b, peeling at a border surface between an inner wall of the case 2 and the sealing body 4, and peeling at a border surface between the sealing body 4 and the solar battery cell 3a, can be suppressed or prevented. Thus, reliability of the solar battery module 1 can be maintained or improved.
摘要（中）：
要解决的问题：提高太阳能电池模块的可靠性。解决方案：在构成太阳能电池模块1的壳体2内部布置有通过布线3b电连接多个太阳能电池单元3a而构成的串。 绳子被封装在壳体2内的密封体4覆盖。密封体4设置有空间5.空间5是用于放松施加到太阳能电池单元3a的应力的部分和来自密封件 通过吸收密封体4的热膨胀，由于密封体4的热膨胀，因此太阳能电池单元3a的断裂，布线3b的断开， 壳体2的内壁和密封体4以及密封体4与太阳能电池单体3a之间的边界面的剥离能够被抑制或防止。 因此，能够维持或改善太阳能电池模块1的可靠性。
