    • PROBLEM TO BE SOLVED: To provide a card type device capable of improving mechanical strength of a mounting substrate with a simple structure. SOLUTION: A memory card 1 includes a mounting substrate 10A and a semiconductor package 10 B in a housing 20. Electronic components such as a communication component 13 on the mounting substrate 10A are covered with a protective member 14 having an electromagnetic shield function. The protective member 14 is formed by drawing process of a sheet metal and forms a storage space by a ceiling 14a and a sidewall 14b and has a curve 14c at a joint between the entire circumference of the ceiling 14a and the sidewall 14b. A flange 14d is provided at the lower end of the sidewall 14b, and the flange 14d is solder-jointed with a ground region 12 of the mounting substrate 14A. The protective member 14 having this structure has a high mechanical strength because of the difficulty of local concentration of stress, thereby the rigidity of the mounting substrate 14A is increased.
