PROBLEM TO BE SOLVED: To minimize swollenness of a cover top surface, which is caused by heat stress in a reflow furnace, in a twin electromagnetic relay having a pair of two electromagnetic relay blocks in one case which enables surface mounting at a low mounting height. SOLUTION: At least one or more protrusions 9, 10 are provided at spools 7, 8 of electromagnetic relay blocks 4, 5 composing an electromagnetic relay body 2 on the cover top plate side. Cylindrical protrusion inserted parts 11, 12, into which the protrusions 9 and 10 are inserted, are provided on a top surface of the cover so as to correspond to the protrusions 9, 10 of the spools 7, 8. The electromagnetic relay body 2 is installed on the cover 3, and the protrusions 9, 10 of the spools 7, 8 are fixed to the cylindrical protrusion inserted parts 11, 12 of the cover 3.
