How it's used

Refers specifically to the permanent record of a criminal conviction maintained by the police. It is frequently used as a warning to deter someone from committing a crime, emphasizing the long term impact on future employment and travel opportunities. The phrase is strictly reserved for legal contexts and carries a serious, cautionary tone.

Examples

It is really not worth it to get a criminal record from fighting.
Do you know that doing this will result in a criminal record?

Common phrases

to have a criminal record
a clean criminal record

Common mistake

Do not confuse this with simply being arrested or questioned by police. A person only gets a 案底 after being convicted of an offense in court, so using it to describe a minor police interaction is factually incorrect.
