PROBLEM TO BE SOLVED: To provide a plate of an inductance component, an inductance component, and a switching power source having the inductance component, with little waste generated on a conductor plate to be a material and provided with a structure capable of reducing manufacturing cost. SOLUTION: On a plate 1 having loop patterns 2, 3, and 4, each pattern can form spiral loop and are arranged so that a triangle having each central point as a vertex can form an equilateral triangle or an isosceles triangle. Gaps 2b, 3b, and 4b are formed between two peripheral ends 2c, 3c, and 4c. Surfaces 1a and 1b are non-insulating surfaces in which insulating films are not formed. The loop patterns 2 and 4, with which terminal parts 6 and 7 project from one of the peripheral ends 2c, 3c, and 4c, and each peripheral ends 2c, 3c, and 4c of the loop pattern 3 are connected via connection parts 9 and 10 narrower than the loop width.
