Abstract
We present results of our 7 mu m deep survey program made with ISOCAM, the infrared camera of ISO (Infrared Space Observatory), We have foun d 15 sources above a 5 sigma(rms) significance in a small selected are a (3' x 3') in the Lockman HI hole. Among the 15 sources, 14 objects h ave also been observed in the near infrared (NIR: similar to 2 mu m). The majority of the 7 mu m sources (11 objects) have NIR counterparts most of which are considered to be galaxies with intermediate redshift s, It is, however, intriguing that two 7 mu m sources have no NIR coun terpart. These objects may be heavily reddened populations which have not been detected by existing optical and NIR deep surveys.
