Summary:PROBLEM TO BE SOLVED: To provide a small reactor with excellent manufacturability, and a coil compact used for the reactor. SOLUTION: The reactor 1 includes an annular magnetic core 11, a coil 12 arranged on an outer circumference of the magnetic core 11, an outer side resin portion 13 for covering the outer circumference of an assembly 10 of the magnetic core 11 and the coil 12, and a sensor hole 13h in which a sensor such as a thermistor is inserted. The reactor 1 can be small by omitting a case. Because the sensor hole 13h is formed by resin molding of the outer side resin portion 13, positioning of the sensor hole 13h becomes easy, and the sensor can be arranged in a predetermined position easily, resulting in excellent manufacturability of the reactor 1. In addition, damage on the coil 12 or the like in forming the sensor hole 13h can be prevented, and damage on the sensor during resin molding is also prevented. COPYRIGHT: (C)2010,JPO&INPIT
