PROBLEM TO BE SOLVED: To provide an electronic element or the like reduced in breakdown voltage variation and high in reliability while responding to a request of miniaturization/thinning. SOLUTION: Two sheets of plane coils 100 having insulating layers 5 having recesses 5a and conductor patterns 4 formed so as to partially occupy spaces in the recesses are prepared and etching surfaces in respective plane coils 100 are made to face the same direction, and thereafter, vacuum-pressed while pinching an adhesive layer 6. By this operation, the breakdown voltage variation can be suppressed, thus improving a breakdown voltage. COPYRIGHT: (C)2008,JPO&INPIT
