PURPOSE:To realize an electronic circuit package in which power source turn-on order can be effectively maintained even if types of the power sources are increased. CONSTITUTION:In an electronic circuit package requiring a power source 10 having two or more types of different voltages, the power source 10 is provided with two types of terminals of early contact terminals to be brought into contact earlier and late contact terminals to be brought into contact later than other terminals when connected simultaneously as power source terminals, and resistors R1, R2, R3 provided at the early contact terminals of the two types of the terminals for every type of the power source 10 in such a manner that the resistances of the resistors R1, R2, R3 are so set that time constants determined by the respective resistors R1, R2, R3 are larger in the power source turn-on order as to supply the power source 10 through the late contact terminals when the electronic circuit is connected to the late contact terminals of power source terminals P1 to P7. |
