Abstract: A semiconductor device is formed by sealing, with a resin, a semiconductor chip (CP1) having an oscillation circuit utilizing a reference resistor. The oscillation circuit generates a reference current by utilizing the reference resistor, a voltage is generated in accordance with this reference current and an oscillation frequency of the oscillation unit, and the oscillation unit oscillates at a frequency in accordance with the generated voltage. The reference resistor is formed of a plurality of resistors, which extend in a first (Y) direction orthogonal to a first side, inside a first region (RG1, RG2, RG3, and RG4) surrounded by the first side (S1, S2, S3, and S4) of a main surface of the semiconductor chip (CP1), a first line (42, 43, 44, and 45) connecting between one end of the first side and the center (CT1) of the main surface of the semiconductor chip, and a second line (42, 43, 44, and 45) connecting between the other end of the first side and the center of the main surface of the semiconductor chip.
