Prasit Chaisrisa, 49, a former MP for the Peau Thai party, confessed to committing lese majeste during a speech to "Red Shirt" supporters of the then-government, shortly before it was toppled in a May coup.
"The judge initially sentenced him to five years in prison but halved the term because he confessed," a Bangkok Criminal Court official told AFP.
His comments can not be reported as they would be in breach of Thailand's lese majeste law -- one of the world's toughest -- that shields the king, queen, heir or regent.
Prasit, a former lawmaker for the impoverished northeastern province of Surin, was arrested just days after the May 22 coup and initially denied the charge. He changed his plea in hopes of a lighter sentence.
"The suspect is a two-time MP and must be... More prudent than ordinary people before speaking," the judge said, giving his ruling.
Since ousting the elected government, junta leader Prayut Chan-O-Cha has repeatedly vowed to crack down on anyone who insults the monarchy, which attracts deep loyalty among the military and Bangkok-based establishment.
A recent study by the Paris-based International Federation of Human Rights said lese majeste cases have surged since the coup, with 18 new arrests made and outstanding cases fast-tracked through the courts.
Critics say the law, Section 112 of the Thai criminal code, stifles free speech and is encouraging a witch-hunt among Thailand's politically polarised society.
On November 18 a radio show host was jailed for five years by a military court for breaching the law.
In August a 28-year-old musician was sentenced to 15 years in jail for writing insulting Facebook posts about the monarchy between 2010 and 2011.
