To provide a multi-functional belt which can prevent deformation of ends and damage of conductor core wires even if force is exerted intensely in a tensile direction.SOLUTION: A multi-functional belt 10 includes: a belt body 11 formed of a thermoplastic elastomer and having a flat belt shape; and a plurality of high-strength core wires 12, 14 and a plurality of conductor core wires 13 embedded in the belt body 11 and extending in a longitudinal direction of the belt body 11. The high strength core wires 12, parts of the high-strength core wires 12, 14, are embedded in substantially a center of the belt body 11 in a width direction. The conductor core wires 13 are embedded offset from the high strength core wires 12 forming the parts to an outer side in the width direction. The high strength core wires 14, the other parts of the high-strength core wires 12, 14, are embedded at the outer side of the conductor core wires 13 in the width direction. Tensile strength of the conductor core wire 13 is smaller than tensile strength of the high strength core wires 12, 14.SELECTED DRAWING: Figure 1 【課題】端部の変形が生じることがなく、引張方向の力が強く作用しても導体心線が損傷することを防止できる多機能ベルトを提供すること。【解決手段】多機能ベルト１０は、熱可塑性エラストマーからなる平ベルト状のベルト本体１１と、ベルト本体１１内に埋設され、ベルト本体１１の長手方向に延びる、複数の高強度心線１２、１４、及び複数の導体心線１３とを備え、複数の高強度心線１２、１４のうち、一部の複数の高強度心線１２は、ベルト本体１１の幅方向略中央に埋設され、複数の導体心線１３は、一部の複数の高強度心線１２から幅方向の外側にオフセットして埋設され、複数の高強度心線１２、１４のうち、他の一部の高強度心線１４は、複数の導体心線１３の幅方向外側に埋設され、導体心線１３の引張強度は、高強度心線１２、１４の引張強度よりも小さい。【選択図】図１
