Electronic circuit with temperature detection element

An electronic circuit with a temperature detection element, the electronic circuit comprising:

• a circuit board;
• the temperature detection element that is mounted on the circuit board to detect an ambient temperature;
• and
• a circuit element that is mounted on the circuit board and that generates heat in conjunction with a circuit operation, wherein
• the circuit board has a conductive pattern, with a heat transfer property, that is electrically connected to any terminal of the circuit element and that transfers the heat generated by the circuit element, the conductive pattern with the heat transfer property is formed in an area outside a range within a predetermined distance from the temperature detection element, and in a case that the temperature detection element is electrically connected to the conductive pattern with the heat transfer property, the connection is made via a linear wiring pattern or a linear wiring member,
• the circuit board is a multilayer board, and
• each of the conductive pattern with the heat transfer property and the linear wiring pattern or the linear wiring member includes a plurality of through-hole vias that is formed in a path from the conductive pattern with the heat transfer property on one end side to the temperature detection element on the other end side.
