    摘要： A temperature sensor that includes a first electrode layer, a second electrode layer, and a thermistor layer between the first and second electrode layers. The thermistor layer includes a spinel-type semiconductor ceramic composition powder containing Mn, Ni, and Fe, and an organic polymer component. In the semiconductor ceramic composition powder, the molar ratio of Mn to Ni is 85/15≥Mn/Ni≥65/35, and when the total molar quantity of Mn and Ni is 100 parts by mole, the content of Fe is 30 parts by mole or less, and the semiconductor ceramic composition powder is 2 μm or less in particle size.

    摘要： A coil component that includes a drum-shaped core with an upper flange and a lower flange, a winding wound around the core, and an exterior resin between the upper flange and lower flange of the core. The exterior resin includes an inorganic filler at 91 to 95 mass % with respect to the exterior resin, and a resin that has more than one glass transition temperature and has a phase-separated structure. A flange spacing distance between the upper flange and the lower flange is 1.0 mm or less.

    摘要： A common mode choke coil as an electronic component includes a laminate. The laminate includes insulating layers stacked in a thickness direction and has a recess sinking in a stacking direction of the insulating layers. The laminate includes at least one coil conductor therein. The recess is filled with a magnetic resin material. The magnetic resin material is formed of a magnetic powder-containing resin that is a mixture of a soft magnetic metal powder and a thermosetting resin. The soft magnetic metal powder has an average particle size of 12 μm or less. The magnetic powder-containing resin contains 65 vol % or more and 85 vol % or less of the soft magnetic metal powder.

    摘要： A rotary encoder includes a shaft and an encoder mechanism that holds the shaft in a rotatably inserted state and detects a rotation direction and a rotation angle of the shaft. The encoder mechanism includes a substrate that rotatably holds the shaft, an insulator portion and a resistor portion provided on one surface of the substrate and alternately provided in the rotation direction of the shaft, a rotor attached to the shaft so as to be integrally rotatable with the shaft, and a slider that is attached to the rotor and alternately slidably contacts the insulator portion and the resistor portion by rotation of the shaft. The insulator portion includes a base material made of a resin, spherical silica, and a fluororesin filler.
