Provided are a glass such as a sealing glass which contains a rare earth element and crystalline particles, a structure made by sealing with said sealing glass, a magnetic head made by bonding using said sealing glass, and a magnetic recording and reproducing apparatus on which said magnetic heads are mounted. According to the glass of the present invention, magnetic heads, and other structures can be bonded at low temperatures and a high bond strength can be attained, and thus, magnetic heads having high-speed sliding properties and magnetic recording and reproducing apparatuses of high reliability can be obtained. The glass can be also used for heat resistant parts such as a pannel glass for a cathode-ray tube and the like.
