Beschreibung
Zusammenfassung:	An object of the present invention is to provide a resin composition and a resin sheet which have excellent photocurability for an active energy ray including an i-line with a wavelength of 365 nm in an exposure step, and can confer excellent alkaline developability in a development step, in the fabrication of a multilayer printed wiring board; and a high density printed wiring board and semiconductor device having a highly detailed resist pattern using the same. The resin composition of the present invention contains: a maleimide compound (A) containing a constituent unit represented by the following formula (1), and maleimide groups at both ends of the molecular chain; and a photo initiator (B) having an absorbance of 2.0 or more at a wavelength of 365 nm (i-line):
