ELECTRIC COMPONENT

PROBLEM TO BE SOLVED: To prevent melting loss of a case by preventing an increase in temperature of a bus bar. SOLUTION: The fusible link integrated bus bar 11 in which a plurality of output terminal portions 16A, 16B are coupled in parallel to a common input portion 12 via fusing portions 15A, 15B are housed in a case configured by coupling a first case 31 to a second case 32, the bus bar 11 is clamped between the first case 31 and the second case 32 at the portion except for the fusing portions 15A, 15B, concave portions 43, 55 are provided in at least the inner surface of the first case 31 and the second case 32 opposing the output terminal portions 16A, 16B of the bus bar 11. An increase in temperature of the output portions 16A, 16B is suppressed by an air layer S1 of the concave portion 43. COPYRIGHT: (C)2010,JPO&INPIT
