The patient has been placed in isolation and health authorities are tracing contacts, the ministry said in a statement, adding that the risk to the wider European population was low.
World Health Organisation chief Tedros Adhanom Ghebreyesus said on Wednesday there was no need for panic.
Tedros told a press conference that in the past 50 years less than 30 Ebola cases had been detected outside Africa.
"(That) means the risk (to the rest of the world) is low, whether it's France or other countries in Europe, they shouldn't overreact, that's what I would like to advise," he told reporters.
DR Congo's Ebola outbreak is linked to the rare Bundibugyo strain of the virus.
It has infected more than 1000 people and killed 267 - generating the largest number of confirmed cases within the first month of any episode of the disease, the WHO said this week.
Experts say the disease was probably circulating for months before it was officially declared on May 15.
Early confirmed cases were identified in urban areas, and infections have since been reported in at least three densely populated displacement camps.
The two largest previous Ebola outbreaks occurred in west Africa - in Guinea, Sierra Leone and Liberia between 2014 and 2016 - and in DR Congo in 2018.
A US citizen treated for Ebola in Germany was discharged earlier this month after no virus had been detected in the patient since May 30.
Tedros said earlier on Wednesday that the outbreak in DR Congo and Uganda continued to outpace response efforts.
"Despite the good progress we have made, we still face major challenges, and the outbreak is continuing to outpace the response," Tedros said.
"Contact-tracing is inadequate, treatment capacity is insufficient and safe burials remain a major challenge, with the health system under pressure," he told reporters.
