摘要： A linear object is composed of a magnesium alloy including, in percent by mass, 0.1% to 6% of Zn, 0.4% to 4% of Ca, and the balance being Mg and incidental impurities, in which, when a creep test is performed on the linear object under conditions of a temperature of 150° C., a stress of 75 MPa, and a holding time of 100 hours, the linear object has a creep strain of 1.0% or less. Zn and Ca interact with each other to improve heat resistance, and thus it is possible to obtain the linear object having an excellent creep property. By incorporating Zn and Ca, in amounts in specific ranges, into the magnesium alloy, it is also possible to obtain the linear object having excellent plastic workability.
