Provided is an electrical cable for which flexibility of an insulating resin portion of the electrical cable is denoted by a secant modulus value, and the flexibility is improved. In an electrical cable (10a), the outer circumference of a conducting body (11), which is formed from wires having wire diameters of 0.15-0.5mm and which has a cross-section area of 20mm2 or more, is covered with an insulating resin (12) which includes a flame retardant. The electrical cable diameter/conductive body diameter is 1.15-1.40. The secant modulus of the insulating resin (12) is 10-50MPa.
