Patent ID: 11169186

Abstract:
A heat-resistance element includes: a heat-resistant substrate including a ceramic material; one or more power wires embedded in the heat-resistant substrate; and a coil structure that is configured by a coil wire extending between start and end points and includes coil segments. The coil segment includes or corresponds to one winding of the coil wire. The coil segment includes: a first conductor extending along the power wire; a second conductor arranged farther from the one or more power wires than the first conductor, the second conductor extending along the power wire; a first connection wire coupling the first and second conductors in the same coil segment; and a second connection wire coupling first and second conductors of adjacent coil segments in the circumferential direction, all of which are embedded in the heat-resistant substrate, and at least the first conductor and the second conductor are not exposed from the heat-resistant substrate.
