PROBLEM TO BE SOLVED: To provide a semiconductor device member that seals semiconductor devices without cracks and peeling and is excellent in heat-resistance, light-resistance, film formation, and adhesiveness. SOLUTION: The semiconductor device member has a heating weight reduction of ≤50 wt.% measured by the method (I) below and a peeling rate of ≤30% measured by the method (II) below. The method (I) measures weight reduction of 10 mg of crushed pieces of the member by thermogravimetric/differential thermal analyzer under 200 ml/min air flow with heating from 35°C to 500°C at 10°C/min of heat-up rate. The method (II) determines the peeling rate by performing on ten pieces of the member a series of steps of dropping liquid for curing semiconductor device member in a silver-plated copper cup of 9 mm diameter and 1 mm depth of a recess to make a semiconductor device member, and letting the member absorb moisture for 20 hours at 85°C and 85% of humidity, heating the moisturized member from room temperature to 260°C in 50 second, holding at 260°C for 10 seconds and cooling it down to room temperature, observing the existence of peeling, and determining the separation rate.
