Abstract: PROBLEM TO BE SOLVED: To provide a ferrite core in which magnetic flux does not partially concentrate, and its characteristic does not deteriorate even if the interval between ends on one side of an outer foot of the core is structured to be larger than that between ends on the other side of the outer foot, which can be downsized, and can facilitate the maintenance of insulation between wiring ends and the outer feet; and to provide a transformer using the same. SOLUTION: Assuming that the direction in which two outer feet 3 which form a pair when viewed from the front end side of the outer foot 3 and a middle foot 4, face each other is set as an X axis direction, and the direction that forms a right angle with the X axis is set as a Y axis direction; the widths W1 and W2 of the middle foot 4 in the X axis direction differ at each point that is equally distant in the normal and negative direction. Thus, the middle foot 4 is asymmetrical with respect to the center of the Y axis direction as an origin point O. The interval G2 between ends on the side of the outer foot 3 which faces the larger width of the middle foot 4 in the X axis direction is configured to be larger than the interval G1 between ends on the other side of the outer foot 3.
