The present invention provides an EGR sensor capable of preventing an electronic component having polarity, such as a diode, from being mounted in a reverse direction, of simplifying workability, and of preventing the generation of an electrical failure in a circuit. A structure for mounting an electronic component comprises: an electronic component 8 including an element portion 8a having polarity and a pair of lead terminals 8b and 8c; and a holding member 2 including a pair of electrode portions 5 and 6. The pair of lead terminals 8b and 8c of the electronic component 8 is formed to have different lengths, and an abutting portion 7 for positioning the element portion 8a of the electronic component 8 is provided in the holing member 2. The abutting portion 7 is formed between the pair of electrode portions 5 and 6 at a position leaning toward one of the electrode portions from their midpoint. When the electronic component 8 is mounted in the holding member 2 at a reverse position, the element portion 8a abuts to the abutting portion 7, and then at least one of the connection portions of the lead terminals is detached from one of the pair of the electrode portions 5 and 6.
