Semiconductor element and semiconductor device

A semiconductor element comprising:

• a semiconductor substrate including a first region and a second region adjacent to each other;
• a first transistor provided in the first region;
• a second transistor provided in the second region;
• and
• a temperature detecting element provided on the semiconductor substrate, wherein,
• the first transistor includes a first source region of a first conductivity type, a first semiconductor region of the first conductivity type arranged away from the first source region, and a first well region of a second conductivity type arranged between the first source region and the first semiconductor region,
• the second transistor includes a second source region of the first conductivity type, a second semiconductor region of the first conductivity type arranged away from the second source region, and a second well region of the second conductivity type arranged between the second source region and the second semiconductor region, and
• the first semiconductor region is connected to the second semiconductor region.
