PURPOSE:To read a display mark on mounting by leading out a peripheral type external electrode for a chip carrier to the side to which a window for applying ultraviolet rays is formed. CONSTITUTION:A chip carrier from which peripheral type external electrodes 2 are led out is set up as a package on the side to which a window 4 for applying ultraviolet rays is shaped. Consequently, the window 4 for applying ultraviolet rays is directed toward the mounting substrate side on mounting. Accordingly, display marks 9 imprinted onto the base of the package can be read, and a protective seal need not be stuck and the window for applying ultraviolet rays be protected. A hole may be bored previously to the mounting substrate for application requiring the application of ultraviolet rays after mounting. |
