Check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

Could be threaded wrong. Could be tension too tight. Could be a bad needle. Could be bad thread (avoid old thread or bargain bin thread). The fabric, needle, and thread may not be compatible, ie the thread is too large for the needle's eye, could be incorrect thread for the fabric, the fabric may be too coarse and is wearing the thread and causing it to break... There could be a burr or nick somewhere that is catching the thread. The thread could be hanging up somewhere in the thread path on the way from the spool to the needle causing it to break when it reaches the needle.
