High-frequency terminator

A high-frequency terminator, comprising:

• a dielectric substrate;
• a metal layer provided at a back surface side of the dielectric substrate;
• a transmission line provided at a front surface side of the dielectric substrate;
• a resistor provided at the front surface side of the dielectric substrate, the resistor being connected to the transmission line;
• and
• a conductor electrically connecting the resistor and the metal layer,
• the dielectric substrate including
• a first substrate part having a first thickness in a first direction, the first direction being from the back surface toward the front surface of the dielectric substrate, and
• a second substrate part having a second thickness in the first direction, the second thickness being less than the first thickness,
• the front surface of the dielectric substrate being flat,
• a step between the first substrate part and the second substrate part being provided in the back surface side,
• the transmission line extending from the first substrate part to the second substrate part and being connected to the resistor on the second substrate part,
• the conductor electrically connecting the metal layer and the resistor at the second substrate part.
