PROBLEM TO BE SOLVED: To provide a three-dimensional sealing structure which can be easily disassembled even after sealing and can be suppressed with a decline in sealing property, and to provide a three-dimensional sealing method. SOLUTION: Portions to be sealed in the three-dimensional sealing structure are formed at facing portions of a cover 10, case 20, and connector 30 via an expandable sealing material 50, and arranged three-dimensionally. The sealing material 50 is compressed at the portions to be sealed when it foams. Accordingly, sealing is carried out among the cover 10, case 20, and connector 30. Out of the portions to be sealed formed at the facing portions of the cover 10, case 20, and connector 30; the one on at least either side is formed with a concave (22 and 32) to arrange the sealing material in. On the periphery of the portions to be sealed of the cover 10, case 20, and connector 30; gas exhaust channels (G1-G3) are formed which communicate with the concaves (22 and 32) and with the external space of the concaves (22 and 32). When the sealing material 50 foams, it is arranged in the concaves (22 and 32) by being compressed by the portions to be sealed. COPYRIGHT: (C)2008,JPO&INPIT
