Claim:
A starter for starting an engine, comprising: a motor equipped with at least one field coil receiving a starting current from a power source to energize the at least one field coil so as to generate a magnetic field; and a current-relaying element being disposed to form at least part of an electric path connecting the at least one field coil and the power source and having a section-reduced portion of which cross section area is less than a cross section area of a winding composing said at least one field coil, the cross section area of the section-reduced portion being decided to cause the section-reduced portion to function as a fuse against an excessive amount of the starting current, wherein: said current-relaying element is a connector bar which connects said at least one field coil and a lead of the motor; a part of the connector bar is connected to the lead of the motor; one end portion of the connector bar is connected to a first field coil and another one end portion of the connector bar is connected to a second field coil; one side of the connector bar is longer than another side of the connector bar on a basis of the connecting part connected to the lead; and the section-reduce portion is located on the one side of the connector bar and the another side of the connector bar.
